Abstract:This paper based on the theory of random process, puts forward a probabilistic statistics model ofmechanism kinematics under stationary and nonstationary condition, and compares it with the researchresult of work1]. We find that the model supplied by this paper is more accurate than work1]. We gavefurther a model of the moving precision ineffectiveness of the mechanism. Based on this model one can es-timate in advance the probabilistic characteristics and reliability of every different kind of mechanism un-der movement. It must be profitable for reliability design.
Keywords:random process  kinematics  mechanism  model of precision ineffectiveness
