Multiphysics Optimization of Traction Motors For E-mobility
Vincent Leconte, Sr. Director, Global Business Development-EM Solutions, Altair

New solutions approaches are supported to perform model setup for OptiStruct, including enhancements to the loads and constraints and optimization responses.

A new option, GRID, is available on the 3rd field of DSHAPE Bulk Entry that allows more flexible shape changes (including normal to the shell surface) as each DSHAPE grid has its own design variable.

OptiStruct offers support for the QUAD element type that defines a 4 or 8 node CQAXI Bulk entry.

An increase of the e-motor operating temperature above critical levels reduces especially the life expectancy of the insulation material, which potentially results in the destruction of the motor. High temperatures also increase winding resistance...
