Abstract: This article analyzes complex bottom collision scenarios and builds a bottom protection safety evaluation technology scheme based on bottom collision conditions, combined with experimental and simulation methods, revealing the mechanism of bottom collision obstacles and battery systems. Based on the linkage analysis of experiments and simulations, an optimal evaluation plan covering multiple damage factors for structural design optimization was created, which provides important support for the reasonable extraction of complex scene working conditions and effective characterization of bottom collision safety issues in new energy vehicles.
