Dynamics Analysis of Multi-Degree-of-Freedom Motion Simulator Based on Hamilton Method

In this paper, a new method is given about using Hamilton principle to establish multi-degree-of-freedom electro-hydraulic mix-drive motion simulator model. And dynamic analysis is performed based on kinetics and kinematics. The simulation is done on multi-degree-of-freedom electro-hydraulic mix-drive motion simulator and Hamilton principle. As cases, some calculating results on dynamic simulation are plotted with the help of Matlab Lagrange. The work in the paper could be seen as a theoretical basis to research motion simulator in depth.
