CAE engineer at GM Defense building multi-body dynamics models to predict chassis loads, optimize suspension and integrate controls, supporting virtual testing and lab transition.
Responsibilities
Work directly with designers, release engineers, validation engineers, test engineers, and chief engineers to support vehicle dynamics and chassis loads and ride/handling assessments on GM Defense projects.
Build multi body dynamics models to establish optimized suspension and steering kinematic and compliance properties.
Virtually integrate chassis tuning parts to meet vehicle-level ride, handling and steering targets.
Optimize body and chassis structure cross-functionally with appropriate teams.
Predict chassis interface loads to facilitate body and chassis systems and create CAE load cases consistent with objective tests and subjective evaluations.
Integrate control systems as required for performance simulations and integrate cross-functional vehicle dynamics model including chassis & propulsion controls and physics.
Act as a single point of contact for users inside and outside of the team and continually improve fidelity of chassis/vehicle models.
Support/enable transition from hardware/on-road based development to lab and CAE environments through collaboration with vehicle development and objective test counterparts.
