Amid concerns about environmental degradation and the consumption of non-renewable energy, development electric vehicles (EVs) has accelerated, with increasing focus on safety. On road, battery packs are exposed to potential risks from unforeseen objects that may collide or scratch system, which lead damage even explosions, thus endangering safety transportation participants. In this study, several predictive models aimed at assessing performances proposed provide a basis for data-driven structural optimization by numerically simulating deformation base plate. Initially, finite element model pack was developed, accuracy verified performing modal analysis various commercial software tools. Then, representative samples were collected using optimal Latin hypercube sampling, followed collision simulations gather data under different conditions. Next, prediction three models—PSO-BP neural network, RIME-BP RBF network—was compared predicting bottom shell deformation. Finally, based error functions. The results indicate these network can accurately predict frontal conditions within specified limits, yielding best performance beyond those limits. developed is able assess mechanical response collision, providing support optimization. It also provides an important reference improving durability design.
