Automotive electromagnetic interference and compatibility can be determined more efficiently using new technology within ANSYS HFSS. As automobiles become mobile hotspots and electronic components are continually added to vehicles, designing for EMI and EMC becomes increasingly important.

A manufacturer of civilian and military aircraft used Ansys EMA3D Cable with integrated MHARNESS solver to improve their understanding of aircraft system lightning response and validate a numerical approach to compliance that compared full aircraft simulations to full physical lightning transient analysis (LTA) tests.

European aerospace pioneer Airbus recently used Ansys EMA3D and MHARNESS to simulate lightning susceptibility for a hybrid cockpit design made partially of metal, carbon fiber composite, and copper foil. The simulation was part of a research and technology project focused on developing the aircraft of the future: an ultra-green and highly cost-efficient air-transport system.

Motor-CAD enables design engineers to evaluate motor topologies and concepts across the full operating range, to produce designs that are optimized for performance, efficiency and size. Motor-CAD software’s four integrated modules—EMag, Therm, Lab, Mech—enable multiphysics calculations to be performed quickly and iteratively, so users can get from concept to final design in less time.

Sanden Manufacturing Europe, a division of the Sanden Group in Japan and part of Sanden Europe, is developing mechanical and electrical compressors for internal combustion engine, hybrid, and electric vehicle (EV) applications. The belt compressor design includes an electromagnetic (EM) clutch based on a magnetic circuit, delivering excellent wear resistance and controlled slippage for smoother operation. Despite its obvious benefits, the generic clutch design was optimized exclusively for the Japanese automotive market. Sanden hoped to validate clutch performance and modify some dimensions or tolerances to localize the design for the European market and meet customer requirements for noise, power consumption, reliability, and cost.

Ansys Motor-CAD is the world-leading dedicated electric motor design software for multiphysics simulation of electrical machines across the full torque-speed range.
