| Abstract: | This paper introduced the basic theory of covariance analysis for stochastic vibration, built a two dimensional model and state equation of farm transport vehicle (FTV) with 5 DOF (degree of freedom), and put forward an object function for evaluating ride comfort of FTV. The relationship between the object function value and the variance of damper coefficient and rigidity of suspension was obtained. It is proved that the optimization of the farm transport vehicle suspension parameter is feasible by means of the method presented in this paper. |
