Research on synchronous accuracy prediction of flexible driving mechanism in series

The androgynous peripheral driving mechanism is a flexible series multi-body system, of which assembly precision is primarily dependent on worker´s experience. In order to improve the assembly efficiency and reduce the assembly cost, a system used to predict the synchronous accuracy for guide assembly is developed based on Matlab-GUI. This system consists of three modules, i.e., data management module, accuracy prediction module and animated simulation module. Each module is briefly investigated in this paper. By predicting the driving mechanism, the theoretical data have been compared with the experimental data. And the synchronous errors of the simulation and animation are also shown on the interface. The results indicate that the predicted values are within the permitted deviation range and agree well with changes of the synchronous errors. Moreover, the prediction system is also of good reliability and stability which can be used to guide the workers for assembly.
