Vehicle tail door lock catch collision abnormal sound judgment method, device and equipment and storage medium

The invention discloses a vehicle tail door lock catch collision abnormal sound judgment method, device and equipment and a storage medium, and the method comprises the steps: constructing a tail door dynamics analysis model, and carrying out the force analysis of a tail door of a current vehicle under static balance and dynamic according to the tail door dynamics analysis model, and obtaining a force analysis result; according to the force analysis result, abnormal sound judgment conditions are determined, the vibration acceleration at the hinge position of the vehicle body is obtained, and the downward peak value of the vibration acceleration is recorded; the downward peak value is substituted into the abnormal sound judgment condition, and whether the abnormal sound risk exists on the tail door of the current vehicle or not is judged according to an output result; according to the method, the problem of difficulty in recognition when the number of abnormal sound parts is large can be solved, the abnormal s
