Abstract
Using the traditional mathematical modeling methods to build dynamics model of motion system of flight simulator — — hydraulically driven Stewart platform, there existed defects such as modeling process is relatively complex, simulation can't provide visual information and so on. To solve the problems, it adopted co-modeling method by combining ADAMS and Matlab/Simulink together, using ADAMS built dynamics model of Stewart platform, using Matlab/Simulink built model of hydraulic servo system and control system, then through seamless interface provided by the software, it established a entire virtual prototype of hydraulically driven Stewart platform. By study and simulation analysis, and then compared with the real Stewart platform through experiments, results showed that the established virtual prototype has high similarity with the real Stewart platform at the performance of dynamics, so it can substitute the general mathematical model to provide theoretical guide and validity in the process of research and development of hydraulically driven Stewart platform. It also proved that the co-modeling method is correct and effective.
