Abstract: The stochastic models of the
usual joints are first established through introducing the
concepts of Clearance Characteristic Element and Clearance
Space. After deriving the probability density function of the
joint clearance and making the probabilistic analysis of the
resulted kinematic errors, the sampling formulas of the
independent variables of the joint clearances are further
deduced. Through Monte Carlo simulation, the statistical
characteristics and frequency histograms of the kinematic errors
are then analysed on computer.
