Electric Motors Multidisciplinary Optimization Platform

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. Learn more at altair.com/simlab-applications

Create detailed hydraulic circuits & actuation systems as part of your multi-disciplinary system simulations, especially for heavy machinery & agricultural equipment, in combination with multi-body systems (Altair MotionSolve®) and granular material systems (Altair EDEM®).

Integrate models for mechanical, electrical, and controller subsystems to simulate your mechatronic product holistically as a system-of-systems. Exchange models and/or co-simulate with other CAE tools either from Altair (such as Altair MotionSolve® and Altair Flux®) or from 3rd parties through the Functional Mockup Interface (FMI) open standard.

Many engineering projects start with CAD geometries. In order to perform design exploration studies and optimization on CAD-based FE models, an automated process is required including CAD, Preprocessor, Solver and Design exploration tools. This example presents a solution to implement CAD tools into an automated simulation-driven design exploration and optimization process.

Due to the large scale nature of Architectural, Engineering & Construction 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.

Altair Flux offers faster and more accurate 3D magnetostatics analysis thanks to the implementation of new integral method. This is extremely interesting for applications with a lot of flux leakage in air, such as sensors modelling. No air mesh is required, dramatically reducing the computation time versus classical finite element method and offering much higher accuracy.

The presentation outlines a solution strategy for how a digital twin of a milling machine is solving mechatronic challenges. To improve cycle times, accuracy, and addressing vibration problems a holistic system simulation serves as the basis for optimization. The efficient modeling of the real system behavior with flexibilities, contacts, gaps, friction, nonlinearities in the drives (incl. saturation effects of motors), power electronics in combination with the control system is the basis for efficient controller design and optimization of the control parameters. The dynamic interaction of multiple system components combining 3D finite elements analysis multi-body dynamics and control system helps avoiding Tracking-, drag-, positioning errors rebound, and accumulation effects.  

Total hip replacement surgeries are seeing an increase in demand, but between 10-20% of these patients may require a revision surgery because of a failure or wearing out of the prosthesis. When an implant causes a change in the typical stresses on the surrounding bone, a phenomenon called stress shielding occurs. Stress shielding increases the risk of bone resorption, bone fracture, and revision surgeries. Topology optimization helps medical product designers develop implants that better match the stiffness of healthy bone and improve the comfort and longevity of the prosthesis. In this study, Altair uses simulation to design an optimized solid-lattice hip implant that reduced stress shielding by more than 50%.

Presentation by Andy Dyer, Senior Tech Specialist at Altair.

In this presentation, we'll take a look at a few examples of e-Mobility systems models built with Altair Activate and Compose and integrated with other tools like Flux, for electromagnetic simulation for electrical machines (motor/generators), for the purpose of simulating power electronics and motor thermal behavior. We'll also take a look at integrating system model via third-party software like CarSim via the use of the Functional Mock-up Interface, which opens the door to a multitude of tools for further system integration, including packages like MapleSim and DSHplus in the Altair Partner Alliance.

Additive manufacturing (AM) technologies have progressed rapidly in the last years. Supported by the recent developments of design optimisation tools and manufacturing capabilities, components and parts produced using AM are emerging more and more into the focus of space industry. The aim of this presentation is to show why AM can be seen a promising manufacturing technique for space industry and in particular for satellite application? Opportunities and challenges that have to be faced to make 3D printed components “flying” on spacecraft are presented and discussed. The re-engineering and qualification approach of the already existing Antenna Support Bracket, that is part of the Sentinel-1 spacecraft, is discussed as a case study to bring this topic into the more tangible context of an industrial project.
