Abstract
Based on the finite element simulation method,Ansys Mechanical software is used to analyze the dynamic response of a certain type of new energy battery frame in the X/Y/Z directions for the structural failure problem under random vibration load.The results show that the stress of the battery frame under the low-frequency vibration condition(2-16 Hz)is significantly exceeded,and the maximum stress in the X direction is 7 428.3 MPa,which far exceeds the yield strength of the material(375 MPa),and the natural frequency(9.5-16.4Hz)overlaps with the excitation frequency band,resulting in resonance risk.Through structural optimization(stiffener design,weld improvement),material upgrade(7075-T6 aluminum alloy,Q355 steel)and damping and damping(silicone rubber vibration isolation pad),the optimized model predicts that the stress in the X direction is reduced to less than 450MPa,the natural frequency is shifted to 11.2 Hz,the resonance interval is effectively avoided,and the weight increase is only 4.3%.This study provides data support and systematic solutions for the design of high-reliability battery racks,which has guiding significance for the lightweight and dynamic performance improvement of new energy storage equipment.关键词
