Dynamic Analysis of 6-DOF Large Displacement Composite Simulation Platform
For the problem of Typical Stewart Platform with small workspace and poor flexibility, the paper proposed a new 6-DOF simulator platform. The simulator platform compounds the three-bar parallel mechanism with moving degrees of freedom and the three-axis turntable with rotating degrees of freedom, it can repeat any attitude of 6-DOF in space. Effectively solve the problem of Typical Stewart Platform with small workspace and poor flexibility. Using Lagrange equation establish dynamic equation of the simulator platform, and using MATLAB in-depth analysis its dynamics. It can provide a reference for the optimal design of structural dynamic of the simulation platform.
