A Nose Cone for Winning: ARUS Andalucía Racing Team Improves Impact Characteristics of Formula SAE Car
When Ana Casares Crespo, a former member of the ARUS Andalucía Racing team from University Seville in Spain, was looking for a final degree project, the team was inspired by the capabilities of Altair’s software. They came up with the idea to improve the impact properties of the vehicle nose cone laminate with the help of simulation. With more than seven students actively using Altair products to improve various aspects of the vehicle, the decision to incorporate Altair tools was an obvious choice. They wanted to make use of the knowledge they had gained from previous studies for structural design of aerodynamic packages.
The team conducted static analysis and topological optimization using tools from the Altair HyperWorks™ suite, which helped them create optimized, lighter components. To improve the impact properties of a Formula SAE car’s nose cone laminate, the Altair solution included structural analysis, and topology optimization verifying structural behavior of a new material. The benefits were improved impact characteristics and fracture properties, and lighter components.

New Simulation Strategies to Slash Architectural, Engineering & Construction Project Timing and Costs
Leading design firms join Altair to discuss high-fidelity simulation solutions for all experience levels to realize efficiency gains up to 40%.
Today, architectural design firms face two primary and often conflicting challenges: increased project complexity and compressed delivery schedules. Due to the large scale nature of AEC projects, frequent change orders, and on-time delivery pressure, more often than not the ability to use traditional simulation methods for design guidance and validation is simply time and resource prohibitive. This situation is further exacerbated when trying to achieve an aggressive design aesthetic, working with new materials, and balancing form and function with sustainability initiatives and construction safety standards.
Recent user experience advancements and the introduction of novel simulation technologies now enable a broader community of designers and civil engineers to confidently and rapidly apply simulation earlier and throughout AEC projects. This webinar will explore this transformational shift and its positive business impact on project timing and costs through the lens of leading AEC design firms and thought leaders at Altair.
BOTTPOWER Designs Lightweight Bracket for Motorbike
BOTT stands for “Battle of the Twins,” a racing category for motorbikes with two-cylinder four stroke engines.
Bottpower is a Spanish motorsport engineering company located in Valencia. They specialize in designing and building custom motorbikes for racing and street use. They design and build parts, systems, and prototypes for other companies.
A project challenge at Bottpower was to design a lightweight stay bracket for their motorbike that could withstand the main and aerodynamic loads. The goal was finding the optimal weight and stiffness ratio to reduce weight while ensuring safety measures. All of this had to be done quickly in order to arrive on time at Addit3D, Spain's most important 3D-print fair, to showcase the bike. The optimal design for aerodynamic loads was found using Altair software.
Reduction of Moving Masses – Streamlined Design for Improved Engine Performance
To expand the rpm range of a motorcycle engine, a new type of rocker arm with lower inertia was needed at KTM. The new rocker arm was required to have the same, or better stiffness and deformation level as the previous design. KTM used Altair HyperWorks™ for nonlinear topology optimization and nonlinear structural analysis to develop the new rocker arm. Thanks to this, the component inertia could be reduced by 15 percent, component mass was reduced by 21 percent, and the stiffness increased by 14 percent which lead to an extension of the rotational speed by 150-200 rpm.
Altair HyperMesh – Mesh Controls

Enabling EV Excellence – Simulation Helps Rimac Improve Structural Design of Innovative Hypercar
Rimac Automobili’s main challenge has been to design a monocoque as a single carbon fiber part with an unprecedented size. Hence, in the development of the monocoque, the main topic to manage was the material, a lightweight, carbon fiber reinforced with epoxy resin. As this carbon fiber is an orthotropic and brittle material, its representation in a finite element (FE) material card is very difficult. To meet this challenge the company introduced Altair HyperWorks™ into their development process.

Development of A new vehicle front sub-frame using Altair Inspire topology optimization
Presentation by Edan Lazerson, CAE Engineer, Plasan.
The Stormrider is a new vehicle which was designed from scratch and developed by Plasan. Altair Inspire was used for Topology optimization In order to find the ""best"" design for the vehicle front sub frame. The available volume (design space), 5 different load cases and target mass were specified and the optimization software calculated geometry to maximize stiffness. The optimization results were complex to manufacture with traditional technologies; the simulation and design teams collaborated on designing a manufacturable front sub frame assembly. The new design was simulated to ensure it will withstand all the required loads. The front sub frame was implemented and tested on the prototype vehicle. The optimized front sub frame proved mechanically sound, while satisfying the mass and geometrical requirements. The early stage optimization reduced the development time, by creating a valid geometry however, the topology to manufacturable design process is not trivial. In this presentation, we will present the mentioned development stages and compare the test results to the simulation predictions.

From MBD to FSI Complete firearm development
Presentation by Konstantin Arhiptsov & by Eitan Maler, Simulation Dept. IWI
Israel Weapon Industries (IWI) at the ATCx in Israel, Netanya on October 30, 2019.
These days, in IWI, complete multi physics simulation is an integrated tool in the development of any new product. The motivation is to completely simulate one or two firing cycles as close to reality. First step is the Multi Body Dynamics simulation to check all mechanism are synchronized and work properly. Second is the explicit simulations - calibrating the mechanical properties of the pistol, in that the springs, contacts, materials and gun powder properties based on one firing cycle. The following is to calibrate the Non Rigid Boundary conditions (NRBC’s). This calibration of boundary conditions which are not completely fixed is crucial to understanding the actual strains and stresses on the parts. One of the approaches was to use known data of the stiffness of arm and wrist, implementing this data into a HyperStudy model to compare and calibrate the results based on a slow motion capturing of a real firing. The results are promising, with high accuracy of the behavior compared to a real capturing of the shooting, up to the point of slider getting to the end of its move – where most of the kinetic energy transform into loads on the frame. The following steps will be to calibrate, using the same method, the return of the slider to it’s original position and perform more than one firing cycle.

E-motor Design using Multiphysics Optimization
Today, an e-motor cannot be developed just by looking at the motor as an isolated unit; tight requirements concerning the integration into both the complete electric or hybrid drivetrain system and perceived quality must be met. Multi-disciplinary and multiphysics optimization methodologies make it possible to design an e-motor for multiple, completely different design requirements simultaneously, thus avoiding a serial development strategy, where a larger number of design iterations are necessary to fulfill all requirements and unfavorable design compromises need to be accepted.
The project described in this paper is focused on multiphysics design of an e-motor for Porsche AG. Altair’s simulation-driven approach supports the development of e-motors using a series of optimization intensive phases building on each other. This technical paper offers insights on how the advanced drivetrain development team at Porsche AG, together with Altair, has approached the challenge of improving the total design balance in e-motor development.
