Abstract: A new finite element method based analysis approach, real time simulation, is brought out applying on the research of mechanism moving steady. Dynamic and mechanic characters of the model system have been through investigated utilizing elastic finite element analysis. The capability and implement technique have been introduced by an example of multi body moving system, which is build by spring joint. The analyses results show that the simulation method is efficacious to evaluate and forecast the dynamics property of the mechanism when it is still on the stage of design. The results show that this method is effective in locating the course of the un-steady moving condition. By the approach of finite element simulation, the non-linear property of mechanism is transformed into linear property, which make that the problem can be solved easily and correctly, as well as getting detailed and virtualized result.
