LightHinge+: Additively manufactured hood hinge

Overview:

In a common innovation project called LightHinge+, EDAG Engineering, voestalpine Additive Manufacturing Center and Simufact Engineering jointly developed a new hood hinge. The project team used the extended possibilities of additive production in order to re-think the component, to re-construct it and subsequently to manufacture it additively. As a result, the new hinge was built with 50% weight reduction compared to the original part, and with the additional advantage to have nearly the entire pedestrian protection functionality integrated within one part. It takes fewer component parts and less assembly steps to build the new hood hinge.

The design was done supported by topology optimization, which finally led to a bionic-like extremely filigree and lightweight structure. Such parts can only be reasonably produced by utilization of AM technology.

Actran Induces Optimization of Electric Motor Drive Design

Overview:

The transportation industry is facing various new technological changes. Among them, the replacement of traditional internal combustion engines by electric powertrains makes new vehicles quieter. Still, new challenges in noise and vibration are rising, in particular during the design of electric motors. In order to develop efficient architectures meeting the expectations both in terms of performance and acoustic comfort, engineers need to access new methods and tools.

Motor design generally starts with the torque as the main purpose of an electric motor is to deliver the required torque at a given speed range. Then, the dimensions of the motor start becoming apparent and efficiency analysis, radial force analysis, structural analysis, and acoustic analysis enter the loop.

“Acoustics analysis should be part of the process and not applied at the end of it” explains Dr. Berker Bilgin, Research Program Manager and Chief Engineer of Canada Excellence Research Chair in Hybrid Powertrain program at McMaster University. If not, it will become difficult to reduce acoustic noise from the motor once the motor design is finalized. Electric motor noise is mainly due to the impact of electromagnetic radial forces (see Figure 1) that excite the stator structure.

Results Validation:

By including Actran in their design process, McMaster researchers developed current control techniques to limit acoustic noise: “Without making any changes in the motor we can actually reduce the acoustic noise just by optimizing the current, because the radial forces are also related to stator excitation, and we experimentally verified drastic noise reduction in switch reluctance motors”, said Dr. Berker Bilgin.

The use of simulation tools has reduced significantly the cost of prototyping and allowed a more advanced analysis of the designed product. Another added value of simulation is of course the attention paid to details thanks to 3D acoustic modelling capabilities. In addition, Actran’s visualization capabilities offer a great possibility for students to train and dig deeper in their research.

In the future, CERC in Hybrid Powertrain team plan on working on how to modify the structural modes without affecting the torque performance of the motor, focusing on current controls of the motors, or modelling the damping ratio of the motor for accurate estimation and reduction of acoustic noise in electric motors.

Safran: Collaborative Simultaneous Engineering Tool for Additive Manufacturing

Overview:

One of the manufacturing processes in which Safran Additive Manufacturing is more specifically interested in, is the Laser Beam Melting (LBM) process. The simulation of this process aims at identifying issues associated with part distortion during the manufacturing process, as well as the potential risks of failure of the part and its supporting structure. Safran called on MSC Software, which offers a solution that uniquely covers the entire manufacturing process, from the initial melting step of the part to the completion of a final HIP treatment (Hot Isostatic Pressing), including all post-processing operations such as a stress-relaxation heat treatment, baseplate cutting and supports removal. This solution is Simufact Additive.

Results Validation:

Safran Additive Manufacturing has taken full advantage of the added value of the Simufact Additive solution in order to secure the integration of the additive manufacturing processes into its “product-process” development processes, both upstream during product design and downstream for the production launch.

Safran Additive Manufacturing is now focusing on extending the use of the Simufact Additive solution to different types of parts and different grades of material, in order to improve the design process for additive manufacturing as a whole. MSC Software supports Safran Additive Manufacturing and the Group in achieving this objective through this solution that integrates into the global additive manufacturing value chain, ensuring a quality and open digital continuity.

Benefits:

The use of Simufact Additive has enabled us to save considerable time in production preparation thanks to the predictive nature of the software, which limits development by manufacturing iterations by using virtual development upstream, but also during the part design phase, by enabling us to anticipate the effects and limitations of the process at the product design level.

One of the added values of the Simufact Additive solution is that it allows us to bring together two activities: engineering and production. On the one hand, people from engineering who design parts with a strong focus on part performance in service, and, on the other hand, the methods office who master the industrial processes and its associated constraints. Simufact Additive is a solution well adapted to simultaneous engineering that facilitates dialogue between the different business activities involved in the same project. In addition, the software is easy to use, with an intuitive, business-oriented interface that allows for quick and easy appropriation/ownership.

Actran Helps Reduce Time to Optimize Design of Active Pedestrian Alerting System by 50%

Overview:

At moderate to high speeds, the only external noises typically generated by electric vehicles are caused by wind resistance or tire noise. As a consequence, electric vehicles present a risk to pedestrians and cyclists, especially those who are visually or hearing impaired or listening to headphones.

Hyundai active pedestrian alerting system Regulations have been issued in both the United States and the European Union requiring that newly manufactured electric vehicles make an audible noise when traveling at low speeds. These regulations have differing requirements for the amplitude and frequency content of the warning sound.

Results Validation:

The simulation results were validated by conducting a 1-volt sine sweep test for both the actual speaker and the simulations. As shown in the figure above, the spectral behavior of sound at 1 meter from the speaker predicted by simulation matches the physical measurements nearly perfectly.

By using Actran to optimize cavity and duct resonances, Hyundai engineers were able to design the speaker to handle low, mid and high frequencies as needed to meet both US and EU regulations while at the same time minimizing speaker size and power consumption. “The simulation results provided by Actran were much more comprehensive than information generated by physical testing, which helped Hyundai engineers quickly iterate to an optimized design in about half the time that would have been required using traditional build and test methods,” Lee said.

Simulating SMC part response with greater confidence using Digimat

Overview:

While Sheet Molded Compound (SMC) materials have been widely used in the automotive industry for some time, recently there has been a move to apply SMCs on more structurally demanding components. Though the material has long been considered quasi-isotropic with relative success, it has become apparent in industry that due to the complex manufacturing process, optimal structural design is not possible without considering the real anisotropic nature of the material.. With growing demand from the market, now is the time to leverage advanced SMC modeling capabilities targeting crash performance.

Results Validation:

Static and crash FEA simulations can now attain an excellent level of accuracy in stiffness and can capture peak load and displacement trends for typical part load cases.

The inner seat part illustrates the proposed workflow from process simulation to structural application. The Digimat simulation achieves a much better fit with respect to test data for most load cases, including head impact (puncture) and provide a good indication of hot spot localizations.

Improving Ride and Handling of Formula Student Car Using Adams Car

Challenge:

Zuura Formula Racing is a student team from the Vellore Institute of Technology in Chennai, India that participates regularly in the Formula SAE student competition organized across the globe by SAE Interna-tional.

For participating teams, the task at hand is to develop a small formula-style race car. Each student team designs, builds and tests a prototype based on a series of rules, aimed at ensuring on-track safety and promoting clever problem solving. The prototype is evaluated for its potential as a production item.

During the course of this project, one of the focus areas for the Zuura Formula Racing team was to ensure good suspension for their vehicle. To achieve this, they needed to ensure that the tires were as perpendicu-lar to the ground as possible to achieve maximum traction. The front geometry had to be designed such that it had a negative camber in jounce. This was an important factor in keeping the wheels perpendicular to the ground, and also to resist body roll.

The main target before the vehicle dynamics simulation engineer at Zuura Formula Racing was to improve the ride and handling of the vehicle by reducing yaw, pitch and roll rates.

Solution:

The Zuura Formula Racing team used the Adams Car software from MSC Software. Adams Car allows students to design and simulate their FSAE vehicles to maximize their vehicle performance. With Adams Car, FSAE teams can quickly build and test their functional virtual prototypes of complete vehicles and vehicle subsystems. FSAE engineering teams can exercise their vehicle designs under various road condi-tions, performing the same tests they normally run in a test lab or on a test track, but in a fraction of time.

Simulation Reality Contest Winner - Vrije Universiteit Brussel

Overview:

The medical industry is moving in a direction towards robotics to help patients in the rehabilitation process. Gait training (over ground or on a treadmill) has become an essential part of rehabilitation therapy in patients suffering from gait impairment caused by disorders such as stroke, spinal cord injury, and multiple sclerosis. A focus on the human in collaboration with a robot puts emphasis on the adaptability, safety, and task specificity of robotic assistance. Hence, in the development of novel rehabilitation prototypes engineers face the challenge of combining suitable design concepts, high performance actuator technologies, and dedicated control strategies in view of improved physical human-robot interaction (HRI). The improvements should lead to a better insight into effectiveness of robot-assisted rehabilitation and ultimately, lead to therapies that are more effective. One of the approaches to facilitate the design process, in terms of development time, functional and safety evaluation, is using computational multibody simulations. Nowadays, multibody modeling and simulations are recognizable as an efficient and relative inexpensive evaluation approach. Due to the continuously increasing complexity of the wearable robots, almost any study conducted in the field of robotics can profit from a simulation of the system behavior, foregoing experiments on a real platform. Moreover, an advantage of using multibody modeling represented by the possibility to predict various outputs that are difficult, dangerous, or even impossible to reproduce in the real experimental setup.

Results Validation:

The 3D model of a novel CORBYS rehabilitation device has been developed and co-simulated with the human body using object-oriented multibody dynamics software, Adams.

Adams gave researchers the additional insight they needed on the push-pull actuation system. The simulation results show that the transmission efficiency of the PPC is dependent on nonlinear friction between the tendon and the sheath. While the friction was influenced by an attached load to the cable and the curvature of the PPC. The simulation results had an impact in defining the actuation system parameters and appropriate control implementation design. These insights helped them present a working concept, which will open doors for further exploration for research and development.

According to modeling experience in Adams, the team confirm that multibody simulation tools are very effective in cases when the main design, technical, and functional characteristics of the real system are accurately reproduced in computational model. In order to obtain a useful functional model, users need a good understanding of the governing mechanics describing a physical system to make relevant choices between numerous simulation platforms.

Benefits:
  • Studied human-robot interaction forces during walking exercise
  • Simulation helped make sure the working prototype met the safety requirements for patients
  • Evaluated the push-pull cable actuation system followed by control strategies optimization

MSC's Marc Helps Ensure Safe Operation of Subsea Oil Drilling

Overview:

In designing heavy machinery, such as those on cranes or oil rigs, small plastic components or rubber seals can be vital to the integrity of those large structures. Stephen Armstrong an FEA Analyst/New Product Development Engineer and his team at Parker Hannifin Corporation work on designing just these types of parts.

Parker Hannifin is a trusted leader in motion and control technologies. Stephen’s team’s main area of focus is on seals that are comprised of hyperelastic materials such as rubber, polyurethane, and other compounds. These seals are used in a variety of applications in heavy machinery, medical devices, military and aerospace industries.

Engineers working with these materials focus on nonlinear analysis in most of their projects, because these materials mainly exhibit non-linear behavior. MSC’s Marc was their tool of choice for simulating such behaviors.

Benefits:

Enhance the seal design and reduced physical testing
