Multiphysics Analysis of E-Motors with Altair SimLab
When designing an electric motor, constraints from different physics must be fulfilled. Electric motor design requires multi-physics analysis: Altair® SimLab® provides a single user experience for all these different physics.
Inside SimLab, Altair® Flux® can be invoked to run the electromagnetic analysis. Once the electromagnetic analysis is finished, the magnetic force information can be applied as loading conditions for noise, vibration, and harshness (NVH) analysis using Altair® OptiStruct®. And the loss distribution (stator/rotor losses, winding loss) can be applied as heat sources for CFD analysis using Altair® AcuSolve®. Finally, Altair® HyperStudy® serves as a multidisciplinary optimization platform for electric motor design.

Introducing Multiphysics Workflows to Accelerate the Design of Electric Motor Driven Systems
Electrification is everywhere! It brings energy efficiency into systems and also helps add new smart functionalities to products. The electric motor is a key element of such systems, converting electricity into mechanical power. It is multiphysics by nature. Electric machine engineers need to take into account various constraints from the early stage of the design, looking at electromechanical performance, as well as respecting thermal and NVH constraints. Simulations need to integrate these multiple physics and also coupling effects. Dedicated tools and streamlined multiphysics workflows are developed in order to reduce complexity and speed up the design.

Workshop: The Role of Simulation From Concept Development to Final Design
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.

Accelerating Crankshaft Modeling with Automation at BMW Motorrad
BMW Motorrad is the motorcycle division of BMW, a German multinational company manufacturing luxury automobiles and motorcycles. With the first motorcycle manufactured in 1923, their current product line includes a variety of shaft, chain, and belt-driven models designed for off-road, dual-purpose, and sports powered by a variety of engines ranging from a single cylinder, various two cylinder (parallel twin, flat twin, boxer etc.), four cylinders inline and six-cylinder inline ones.
BMW Motorrad faced a challenge with their model build processes, needing to move previously outsourced crankshaft modeling work in-house while also reducing lead time. Through a semi-automated modeling process based on Altair SimLab, BMW Motorrad developed scripts which reduced FE model generation time down 80%, from 2 weeks of manual work to just half a day.
Ruediger Ott, HyperWorks Business Development at Altair, presents a use case from BMW Motorcycles who found that they could significantly reduce the model build time of their powertrain assemblies with SimLab, making use of the automation capabilities to minimize manually effort and refinement.

Sound and Simulation: Designing a Smart Speaker
Speaker design and analysis, especially for a more complex product, system, or component, often requires building multiple simulation models. The loudspeaker development process involves multi-physics and multiple sources in parallel, to multiple simulation runs for prototyping, testing, and validation. This results in separate models for nonlinear analysis of strength, thermal analysis and stiffness, noise, vibration, and acoustics. Even though each model isn’t always built from scratch, typically the use of different solvers for each attribute will require that models need to be converted from one solver format to another. This practice is not only time consuming but frequently error prone resulting in an inefficient use of engineering time.
