Mechanism action reliability is one of the most significant standards to test the quality of various mechanisms. In the previous study on the mechanism reliability, the reliability of strength and longevity was paid more attention to while the study of mechanism action reliability was ignored. With the mechanical development of highly accuracy and highly automation, the issue of reliability that takes the accuracy of mechanism action as the main standard becomes outstanding, and which is one of the most important factors to control the improvement of mechanism reliability. Therefore, the systematically study on the theory of mechanism action reliability and its analytical method is greatly meaningful to the improvement of the mechanical products.On the analysis of the mechanism action reliability, most previous study is based on the establishment of math model, the method by which is applied difficultly on the complicated mechanism affected by many factors. Whereas, on the basis of extendedly research on theory and analysis method of mechanism action reliability on hand, combined with mechanism kinematics, and the theory of mechanism error analysis for motion and interference model, the math model of mechanism kinematics is established, and the formulate of mechanism motion reliability is presented considered manufacture error and joint clearances.The collaborative technique between the software of ADAMS, CAD and VC++ is comprehensively analyzed, a simulation method of mechanism action reliability is proposed, i.e. on the foundation of the ADAMS/View study, mechanism parametric model is established. Furthermore, the model is realized every time in the circle of simulation and the outcome is saved; then applied with the User-Written Subroutine, the outcome of the simulation is further calculated and computed from which the action reliability can be got.According to the technical plots stated above, the mechanism action
