Aiming at the vibration cracking problem of a vehicle BCM bracket,a finite element model of the BCM bracket is established to do the random vibration fatigue analysis.The analysis results are consistent with the cracking position of the random vibration test,which verifies the effectiveness of the BCM bracket's random vibration fatigue analysis.Lastly,the structure of the BCM bracket is optimized,which effect is good.
