The growing integration of compact, high-speed electric powertrain components is increasing the need for detailed simulation-led engineering across the automotive sector. BMW is using SIMULIA technologies from Dassault Systèmes to analyse the behaviour of electric drivetrain components including rotors, gearboxes, housings and roller bearings under real operating conditions. The company is combining Abaqus, Simpack and Tosca to perform structural, vibration and system-level simulations focused on stiffness, friction, acoustic behaviour and housing deformation. BMW is also using simulation-driven optimisation to evaluate lightweight drivetrain designs and identify performance issues earlier in the development cycle, while working towards migrating these workflows onto the 3DEXPERIENCE platform.
