Abstract
Electric vehicles are ushering in a new era of travel, transforming transportation, and shaping the future of mobility. The transition to electric vehicles requires development of new methodologies that effectively interpret and simulate the complex systems in these vehicles. The electric drive is one such system and it constitutes a critical component for the electrification of vehicles. In the design and development of such an electric drive, a stator vibration durability test was performed. It indicated that a different varnish level on the stator might impact the durability of the stator assembly by changing the mechanical connection between the stator laminate and the winding. To analyze this behavior computationally with the Finite Element Method (FEM), a simulation strategy for the evaluation of the dynamic response of an electric drive stator was developed.
This presentation illustrates a method to model a laminated stator core with Abaqus cohesive elements. The simulation method uses the Abaqus Standard finite-element solver code and utilizes linear dynamics capabilities along with a submodeling technique.
