CAE Powertrain Durability Engineer

Description:

• Perform structural stress and durability CAE analyses of 3-in-1 and 2-in-1 EDU system and components, and use the results to provide guidance to improve structural design validation for current programs and future products.
• Perform eDrive, PTU, RDM & IRDA/IFDA housing topology optimization to improve the stiffness and NVH target while reducing the total mass, improving the overall fuel economy of AAM products.
• Perform driveline system NVH thermal sensitivity through driveline system dynamics and bearing dynamics to improve the NVH robustness.
• Perform bolt joint sealing and bolt slippage performance analysis of AAM drivetrain products with various gasket designs and sealing strategies.
• Perform PTU, RDM & eDrive assembly mobility analysis to improve AAM driveline products NVH performance;
• Perform Rotor and Stator interface design calculations

Required Skills and Education:

• Master degrees in mechanical engineering with five years experiences of automotive industry finite element analysis or a PhD with two years of experience. PhD preferred.
• Nonlinear stress and fatigue analysis of drivetrain components using Hyperworks, Abaqus, Nastran etc. software;
• Bolt joint sealing and bolt slippage performance analysis of powertrain system under complex loading and thermal conditions;
• Topology optimization analysis of powertrain components using Optistruct software;
• Mobility and modal frequency analysis of drivetrain system using Nastran;
• Expertise in the areas of solid mechanics, numerical analysis methods, fatigue and optimization methods and weld distortion and durability analyses.
• Prior experience in 2-in-1 or 3-in-1 Electric Drive Unit design and development required
• Prior experience in performing Park System and Disconnect System analyses required
• Exposure to Mechatronics CAE, Emag and Thermal analyses will be considered a plus
