In order to reduce the cost of the vehicle,the aluminium battery pack of the tram was considered to be replaced by a steel battery pack,but the simulation analysis of the whole vehicle side pillar collision condition found that:due to the increase in the mass of the steel battery pack,the vehicle side surround deformation is serious and the shell of the battery pack is deformed too much in this condition,so the vehicle has thermal runaway risk.In order to improve the crashworthiness of the vehicle and the safety of the battery pack at the bottom,the thickness of the threshold beam was selected as the optimisation parameter and the vehicle was simulated and analysed based on the orthogonal test method in order to find the optimal solution.The steel and aluminium battery packs are then compared and analysed from multiple angles to illustrate the advantages of each,providing a basis for subsequent vehicle manufacturers to select different materials for different models of battery packs.
