Vehicle material mechanical property monitoring method

The invention relates to the field of vehicle material mechanical property monitoring, in particular to a vehicle material mechanical property monitoring method. The method comprises the steps of calculating a comprehensive stability index of each vehicle according to a speed sequence of each vehicle in a historical time period, a compression length sequence of a spring and a telescopic distance sequence of a piston rod; calculating the similarity of the compressive strength of different vehicles according to the speed sequence of each vehicle in the historical time period, the compression length sequence of the spring, the telescopic distance sequence of the piston rod and the comprehensive stability index; coding each vehicle according to the similarity of the compressive strength of different vehicles; and training the network by using the compression length sequence of the spring and the telescopic distance sequence of the piston rod of each vehicle in the historical time period corresponding to each numb
