Mechanical Analysis and Optimization of Cast Aluminum Box Structure for Power Battery
The power battery box carries the power battery,and its mechanical properties affect the structural safety.In 2020,the"GB 38031-2020 electric vehicle power battery safety Requirements"was promulgated,which involves several test items,includ-ing vibration,mechanical impact,simulated collision and extrusion.A power battery box body has carried on the preliminary analysis of statics and modal simulation,and improved the part structure design,finally based on the mechanical testing require-ments in the national standard,completed the power battery box body vibration,mechanical shock,simulation of collision,squeezing several simulation analysis,the simulation results show that the mechanical properties can meet the new gb test battery enclosure,Finally,the battery box also passed the national standard test.
