From 2012 Automotive Simulation World Congress:
Robust sealing of the electric motor case is important to avoid corrosion and function failures. This study investigated an actuator case made from fiber-filled polyphenylene sulfide (PPS) or polybutylene terephthalate, bolted to an aluminum foundation housing. To evaluate the actuator case-to-foundation housing seal, CAE analyses were conducted using ANSYS Workbench. The analyses included evaluation of the rubber seal between the electric park brake and foundation brake housing subject to different temperatures in the installed condition.
