Validating Analysis on Influence of Vehicle Structure in Considering Crash Compatibility

Abstract:

With the finite elements analysis and topological optimization algorithm, the head structure of four-wheel independent drive pure electric vehicle is regarded as optimization objective. The vehicle’s head structure is optimized by LS-DYNA and LS-TASC on the condition that whether considering the compatibility constraint. The mass fraction curve, the mass distribution convergence curve and optimization results are used to analyze the influence of vehicle structure when considering crash compatibility, and verify that good crash compatibility means homogeneous geometric structure and homogeneous impact force in contact surface.
