摘要
Aiming at the problem that it is difficult to control the mechanical assembly error in the process of transmission, this paper presents a dynamic model simulation method of error transmission system. By analyzing the component structure of worm meta-action assembly unit, combining the error source and assembly dimension chain, the corresponding error transfer model of mechanical meta-action assembly process is established, and the assembly error transfer digraph is constructed; Based on the directed graph and using Vensim_ Ple software, the assembly error transfer accumulation model under system dynamics is established and simulated. The simulation results show that the assembly error transfer accumulation of worm rotating meta-action unit is a step-up trend. The comparison between the test results and the simulation results shows that the dynamic model of the error transfer accumulation system established has a high accuracy. The simulation results have a certain practical significance for guiding the assembly error control in the transfer process.
