By automating the crankshaft modeling process using Altair SimLab, BMW Motorrad, the motorcycle division of BMW was able to significantly reduce their model creation time, and enable accuracy in budgetary forecasting and planning. As a result of making it an inhouse resource, they were able to gain flexibility and consistency in model quality, with a high-degree of efficiency with iterations.
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.
Customer Stories, Technical Papers
An Altair customer for many years, Schneider Electric at first used only Altair Flux; now the company has extended their usage to several more software products in the Altair HyperWorks suite, including solutions such as Activate, MotionSolve, OptiStruct, and others to apply co-simulation in their development processes. Schneider feels their collaboration with Altair is more like a partnership than the standard supplier-OEM relationship.
Traction-based, patented NuVinci® transmission is a continuously variable planetary (CVP) technology enabling performance and efficiency improvements for machines that use an engine, pump, motor, or geared transmission systems. Fallbrook Technologies has been working on improving oil flow inside the NuVinci products as it affects the transmission’s efficiency, durability, power, capacity, and cost. Altair worked with Amazon Web Services (AWS), a secure cloud services platform, to provide an integrated solution to Fallbrook including advanced GPU hardware, high-performance computing (HPC) and the nanoFluidX software through industry-leading workload management and job scheduler Altair PBS Professional™.
Mabe is a Mexico-based international appliance company designing, producing and distributing a wide spectrum of home appliances such as washing machines, dryers, cooking ranges, refrigerators, air-conditioners, microwaves, etc. Altair technology has enabled Mabe to increase the capacity of their washing machines by 35%, and the spin speed by 24% while reducing the cost per cubic foot by 10%.
HyperWorks’ Simulation Technology Enables Godrej to Streamline Sheet Metal Tooling Processes
Using Altair HyperForm, HyperWorks’ stamping simulation technology, Godrej was able to design and
fine-tune a successful tool for a rear fender, while minimizing die testing time by reducing physical
trials. Leveraging numerical analysis, Godrej was also able to predict the size, shape and location of
the blank accurately. HyperForm’s ability to visualize failure in incremental simulation enabled them to
finalize the draw bead location and characteristics.
