　　Abstract：To investigate whether the rigidity and modal analysis of the multi-universal battery system and its adapter bracket meet the vehicle performance indicators， this paper separately carried out the mounting point rigidity of the adapter bracket， the strength of the battery system and the adapter bracket， and the battery system loading. The modal analysis before and after the adapter bracket simulated the feasibility of the general battery system connecting the whole vehicle through the adapter bracket from the above three aspects. The final results show that the simulation results of the battery system and its adapter bracket meet the vehicle performance indicators. This analysis method and process also provide a valuable reference for the development of other battery systems and their adapter brackets in the future.
