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.

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.

Hyundai Motor Company

Products:

Actran Acoustics

Industries:

Automotive

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.

Major automotive OEM

Digimat

Industries:

Automotive

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.

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.

Overview:
概要  この論文は、津波サバイバルカプセルの設計、工学、および検証におけるMSCソフトウェアの使用を概説しています。津波は世界中の135カ国の沿岸地域社会にとって絶え間ない脅威となっています。2004年12月、インドネシアのスマトラ島西岸でマグニチュード9.1の地震が発生しました。この地震により、津波は最大30メートル(98フィート)まで上昇しました。津波はおよそ23万人の命を奪いました。日本の仙台市では、2011年3月、マグニチュード9.03の地震が発生し、40.5メートル(133フィート)の高さに達した津波が発生し、およそ2万5,000人の命を奪いました。  日本気象庁による将来の東京湾南側の地震・津波事故の予測では25万人を超える犠牲者となっています。津波にさらされる沿岸の総人口は250万人を超えています。  そのような自然災害で、このような数の人々を失うことは、医学、深宇宙探査、ナノテクノロジ―などの科学的なブレークスルーの時代において、正当化できません。したがって、サバイバルカプセルは、このリスクの一部を軽減し、これらの地域の人々に代替選択肢を提供する試みです。  津波イベントは非常に危険な環境であり、大きな物体の衝撃、鋭い物体の貫通、動的な衝撃、衝撃および熱などの荷重ケースに耐えなければならないように構造に多くの重要な厳しい要求を提示します。  これらの条件を正確にシミュレートするために、IDEA Internationalはさまざまな航空宇宙関連プログラムで毎日運用している、MSCソフトウェアを使用することを選択しました。カプセルの解析のために、NASTRAN、DYTRANおよびPATRANを利用しました。
Results Validation:
解析と試験の相関 壁面衝突の相関について  剛体壁とサバイバルカプセルとの衝突を、DYTRANを用いてシミュレートしました。カプセルは、全占有重量で17.3mphの初期速度に設定されました。シミュレートされた変形が21.59×17.78cm平らな領域によって図8に示されています。  サバイバルカプセルを試験するために、10フィートから落下させて、コンクリート床に17.3mphで衝突させました。この落下は、図8に示すように、19.5×22.5cmの恒久的に変形した平らな領域を生じさせました。  恒久的に変形した領域の面積は、シミュレーションモデルと比較した場合、試験品で14.2%大きくなりました。この差異は許容範囲内ではありますが、DYTRANモデルにドアをモデル化することによって、より密接な相関が得られた可能性があります。ドアがなくても、ドアの切開部は自由に圧縮でき、カプセルの永久変形を軽減することができます。 貫通の相関について  短い剛体棒に衝突するカプセルをシミュレートするために、重い剛体棒を固定された平板に突き刺さるように発射しました。棒は、運動量伝達が固定棒に当たる可動カプセルと同等であるように、カプセルと同じ質量を有するようにモデル化されました。DYTRANで実施されたシミュレーションによれば、カプセルは、5mphで剛体棒に直撃した後で、深さ22.4mmの衝撃窪みを残します。図10に変形を示します。  さらに、シミュレーションでは、剛体棒に15mph以上の速度で衝突すると、カプセルが貫通することが示されています。テスト結果は、これらのシミュレーションが控えめであることを示しています。図11は、16.29cmからの落下試験(4mphに相当)の結果を示し、7.38mmの永久変形を生じました。  テストとシミュレーションの違いは、いくつかの要因によるものです。第1に、カプセルを所望の衝撃ゾーンに正確に落とすことが難しい課題でした。したがって、すべての衝撃試験は、パネルのたわみを減少させる硬いフレームの近くで発生しました。また、カプセルシェルは湾曲しており、シミュレーションモデルが移動する棒エネルギーのすべてを吸収するところで、剛体棒がかすめることを可能にします。さらに、シミュレートされたプレートは、半球が加工されひずみ硬化し延性が低下したにもかかわらず、理想的な材料条件を使用します。シミュレーションとテストとの間の相関が低いにもかかわらず、シミュレーション貫通法は控えめであり、将来の設計の繰り返しに使用できることが確認されています。
