Introduction
About
Flux-OptiStruct coupling allows making NVH analysis or static analysis in OptiStruct using the magnetic forces exported from Flux.
The various concerned applications according to the coupling are: Motor, actuator, busbar ...
This specific document gives the optimal workflow to follow in HyperMesh, Flux and OptiStruct to make the NVH analysis on a motor.
For other types of analysis (time/static forces, time/static heat sources, temperature), please refer to the online help documentation.
Concerning the software version to use: Flux2018.2 (mandatory), HyperMesh 2017.2 (strongly advised) and OptiStruct 2017 (advised).
Interest
Magnetic forces which exist in a motor on the interface between the airgap and ferromagnetic part (stator or rotor) can involve motor vibrations with annoying noise.
The Flux-OptiStruct coupling allows predicting and evaluating those vibrations.
