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.

Concept Design for Plastic Parts - Better and Earlier Decisions with CAE Driven Design
Traditionally, products are created with a draft, which is then specified by taking into account external factors. The next step is to validate, test them as prototypes and adapt the design. If simulation is used as a virtual test, this cycle can be accelerated.

The foundation for a successful design is set in the concept phase.

This raises the question of how simulation can be used as a motor for creative solutions and how it can be used as a groundbreaking basis for decision-making in the early phase of product development.

With the simulation-driven design approach, you can achieve early design maturity, efficient material utilization and shorter development times in the development of complex plastic components. Using the example of a front-end module, Code Product Solutions and Altair will demonstrate efficient product development in the recording "Concept Design for Plastic Parts".

Design for Additive Manufacturing with Topology Optimization
Presentation by Avishai Warszawski, Mechanical Designer at IAI, Israel Aerospace Industries at the ATCx in Israel, Netanya on October 30, 2019.

The goal of this project is to design a lightweight and stiff support bracket for delicate coaxes which are attached to an electronic unit. The machining design of this bracket, although very light in weight, did not provide the required stiffness and was also very expensive to manufacture. The best approach for design was only realized after the AM team was requested to find a solution. Topology optimization with Altair tools was used to define the best shape that provides the best solution. Finally, the bracket was printed in an SLM machine from AlSi10Mg. In the near future it will be qualified by dynamic tests in accordance with the defined environmental loads.

From MBD to FSI Complete firearm development
Presentation by Eitan Maler, Head of Simulation Department & by Konstantin Arhiptsov, Simulation Engineer
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.

Dynamical RCS - Helicopters in pulsed Doppler radars image 
Presentation by Tal Oz, Officer, Israeli Air Force.

Many modern radars measure the radial velocity of airborne targets using Doppler shift to distinguish between real targets and clutter (trees, clouds, birds). Radial velocity and Doppler shift are directly related for regular airborne targets such as Boeing 747 but even a standing still helicopter will produce some sort of measurable Doppler shift. It is a computationally difficult task to find the relevant helicopter RCS but a feature provided by Feko, the ""Numerical Green Function"" can dramatically improve computation time of such problems. The lecture will begin with relevant Radar and RCS introduction, some highlights of important Feko features and dynamic RCS results of a CAD model of a helicopter.
