This workshop demonstrates how a simulation-driven design approach to product development can have a drastic impact on the performance, design time, and profitability of a new product. Using a belt sander tool as a demonstration model, our presenters show how Altair’s design and simulation technologies can conduct a concept design analysis and optimization of the sander external housing to improve stiffness and reduce weight. They go on to show how we can simulate the manufacturing process itself by looking at filling, packing, cooling and warpage of the plastic housing; before concluding with a series of stress analysis and validation studies such as a virtual drop test, 3-point bending simulation and even a study of the effect of the heat transfer of the electric motor. This is a valuable session to see how simulation technologies can be used throughout the design process, adding value and reducing development time at each stage.

Product engineers are under constant pressure to reduce costs, improve quality and increase the throughput of manufacturing processes. Applying a simulation-driven design for manufacturing (SDfM) approach to product development can help understanding the product manufacturability early in the design cycle, while considering various design alternatives and choosing the best performing, manufacturable design up front. After a brief introduction of the metal forming process, the presentation will explore a typical use case of a sheet metal part - subject to static and dynamic loading – showing how simulation can be very effective in reducing cost for parts redesign and dies modifications, while providing engineers with valuable insights on the manufacturing process and product performance.

The goal for any design, structural and manufacturing simulation is to predict and fix defects early in the product development. This panel will discuss how design and simulation tools are helping engineers to be efficient. Experts will share their thoughts on current and future trends in manufacturing, focusing on how designs evolve using manufacturing simulations.

For several years now, co-simulation between Multibody Dynamics (MBD) codes like MotionSolve and Discrete Element Method (DEM) software like EDEM has been used for many applications such as vehicles and material transportation. One missing link has been a realistic tire model that not only could interact with the soil material in a realistic way but also show the influence of varying tire pressure, change in contact area and pressure distribution over said contact area.

For very soft material such as deep mud with a high-pressure tire, using a rigid wheel is a decent approximation. But for tires on harder surface, this method has several short comings. For example, a rigid representation of the tire will have neglectable rolling resistance while the pressure distribution on a real tire has its peak well ahead of the centerline of the tire producing a resisting moment to the motion. The contact patch area will in reality not depend on sinkage, but the sinkage is dependent on the contact area that is dependent on load and internal pressure.

This presentation introduces the new PM-FlexTire model that is integrated in EDEM and will work with MotionSolve. Requirements for creating and correlating the tire model is presented together with several application examples on mud, clay and gravel beds.

The chassis of a the RAVO 5 iSeries street sweeper has been a proven design that has remained relatively unchanged since the mid-60’s. However, due to increasing weight and size requirements, as well as possible changes to the driving mechanism, an overhaul of the chassis platform is needed. To develop a new (modular) chassis, which is suited for upcoming and future changes, a CAE-driven design approach is chosen, which is being performed by VIRO. When using computer-aided engineering (CAE), the chief problem is to define or estimate the acting loads and / or boundary conditions on a structure. In case such a structure is dynamically loaded, such a determination is further aggravated. Furthermore, if that structure is a chassis, a wide range of load cases and interconnected systems (e.g. tyres, suspension) effect the multifaceted loading behavior.

By utilizing multibody dynamics (MBD) and creating a MBD-model of the current street sweeper, a first step is taken towards developing a new (modular) chassis. The calculated loads and moments acting on the suspensions and chassis are quantified for e.g. several worst case scenarios, which allows for well-founded decisions in relation to the new design. Furthermore, these load conditions can be used as input for future topographic optimizations and / or stress analyses. An important part, when creating a CAE-model, i.e. in this case a MBD-model, is the validation of that model by experiments and /or analytic formulations. Consequently several calculated load cases have been tested in the field and in mutual cooperation. A subsequent verification shows that the measured accelerations correlate well with the calculated accelerations from the MBD-model.

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. Presentation at the ATCx in Israel, Netanya on October 30, 2019.

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.

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.

The first part of the presentation shows the detailed process of building the multibody system of an actuated exoskeleton in MotionView/MotionSolve (MV/MS). The required movements are transferred to the corresponding joints by “Motions”. By this the exoskeleton can Stand Up, Walk diagonally across the floor and Sit Down. In the second part the “Motions” in MV/MS are replaced by controllers (position control) whichdeliver a certain torque to actuate the exoskeleton. The main topic here is the implementation of the co-simulation between Activate and MV/MS. In the end the presentation gives a quick outlook of similar works at the University of Applied Sciences Kaiserslautern in Germany.
