A Teaching Case of Multi‐Physics Analysis of Power Battery Protective Structure for Mechanical Optimization Design Course

ABSTRACT

To address the limitations of physical field simulation and optimization in the mechanical optimization design course, this study develops a comprehensive set of multi‐physics simulation teaching cases centered on power battery protection structures. The proposed teaching case integrates three core modules: fluid‑thermal coupling simulation, mechanical loading response simulation, and multi‐objective optimization design. It systematically elaborates the corresponding theoretical foundations, modeling workflows, and key parameter configurations, and further refines the teaching design, class hour allocation, and teaching assessment mechanism. Preliminary teaching practice indicates that students report high satisfaction with this case. The case effectively improves students' practical abilities in multi‐physics simulation modeling, structural performance analysis, and multi‐objective optimization design. With strong teachability and engineering reference value, it provides a valuable reference for the construction and reform of similar professional courses.
