Multiphysics Powertrain Cooling, Fatigue and Durability Analysis
Thursday, September 4, 2014 @ 11:00 AM EDT (8 AM PDT/5 PM CET)
The success of a durability and fatigue analysis hinges on the accuracy of the known stress, including the stress from thermal expansion.
Vehicle durability and fatigue analysis requires structural FEA and CFD co-simulation at a component and system level. In this webinar, Altair’s approach to durability and fatigue analysis in the context of vehicle underbody cooling will be outlined.
A system level co-simulation case study will be presented, utilizing HyperWorks Virtual Wind Tunnel interface to AcuSolve to compute underbody aerodynamics and conjugate heat transfer to an engine block assembly. Temperature distributions are then mapped to OptiStruct for static stress and displacement in the cylinder head.
