This article discusses the mathematical model and programming of computer simulation of tank stochastic system. In this paper, Monte-Carlo method is used to simulate the input of ground and the state equation of the vehicle is stochastic. The Rugge-Kutta method is used to solve the initial value problem of ordinary differential equations, and the probability response is obtained Mean value, root mean square value, probability density function and power spectral density function. The FORTRAN program which is suitable for the simulation of the stochastic dynamic system of the general crawler combat vehicle is compiled for the mathematical model studied and debugged and calculated on the SIMENS 7760 computer with FOR1 compilation system. In this paper, some results of eight kinds of tank vehicles are introduced. Using the given curves and charts, the dynamic characteristics of the tank can be described. The calculated data can be used for the tank system analysis to provide quantitative reference for the overall performance prediction and overall optimization of the vehicle.
