摘要：
Aiming at the difficulty to accurately evaluate and predict the movement performance of mechanical products in the design stage, the research method based on meta-action motion process was proposed. By Function-Movement-Action (FMA) structured decomposition, all basic meta-actions of mechanical products were obtained. Through analyzing the motion process of a single element, the key error was mapped to the motion parameters, and a complete motion equation of motion was established. The motion model of meta-action chain was obtained based on its relations of motion transfer and coupling. The whole system was simulated by MATLAB and the simulation results were used to compute motion reliability. The experimental results showed that the simulation method of the element motion theory were good in consistency with the experiment results of the Monte Carlo simulations method. With the new approach, the numbers of tests were significantly reduced and the experimental cost was saved. © 2020, Editorial Department of CIMS. All right reserved.
