Overview:

Team Predators is a student team of D.Y. Patil College of Engineering, Akurdi, that has participated in several national automotive competitions and events since 2009. The team participates regularly in BAJA SAE India and BAJA SAE International competitions and has won several accolades in the past.

The team specializes in single seater All-Terrain Vehicles (ATV) and has been on a quest to manufacture the lightest and most durable All-Terrain Vehicle (ATV).

While preparing for its entry for 2019, the team was facing some challenges with respect to the design of dynamics of the vehicle. The vehicle that the team had showcased in the previous year (2018) was facing an understeering issue, which affected its manoeuvrability. In the year before that, the vehicle that was showcased had a tendency towards excessive rolling, which compromised the stability of the vehicle. This resulted in the driver of the vehicle being underconfident during the 4-hour endurance race of the competition. The team was keen to address all these issues in its 2019 entry.

Simufact
Simufact Additive

Industries:

Automotive

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.

McMaster University

Products:

Actran Acoustics

Industries:

Automotive

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

Products:

Simufact
Simufact Additive

Industries:

Aerospace

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.
