摘要
电池包的疲劳耐久性能是电动车设计过程中重点考察的指标之一。文章基于模态叠加法,以PSD谱为激励,使用时域法对某电动车电池包进行振动疲劳分析,找出危险点,指导开发设计。
Durability of the battery packs is one of the important index during the process of the electric vehicle design. The article analysis the vibration fatigue life with the modal superposition method based on PSD to find out the dangerous points The result is useful for its design
