摘　　要：某型号空调室外机在随机振动加严测试8小时后电机支架底部折弯处开裂,为探究开裂失效原因,对电机支架与底座固定位置进行分析,并通过理论计算得出固定位置对电机支架折弯处应力幅值的影响,结合有限元仿真分析对多种方案进行的模拟验证解决电机支架开裂问题,为电机支架的结构设计提供了优化思路。After 8 hours of random vibration testing,the bottom of the motor bracket of a certain model of air conditioning outdoor unit cracked at the bend.To investigate the cause of the cracking,the fixing position of the motor bracket and base was analyzed,and the impact of the fixing position on the stress amplitude of the motor bracket bend was obtained through theoretical calculations.Through finite element simulation analysis,multiple simulation scenarios were tested to solve the cracking problem of the motor bracket,providing ideas for the structural design of the motor bracket.
