一种新型全自动折叠舞台动力学分析

Kinematics analysis of a kind of automatic folding stage

研究了全自动折叠舞台折叠与展开过程的运动状态并做出详细动力学分析。对单组舞台板进行动力学理论建模,得到各机构动力学解析式,采用MATLAB软件绘制动力变化曲线。选择适当舞台参数建立动力学模型,基于ADAMS软件进行动力学仿真,将仿真结果与理论分析值进行对比,验证分析的正确性。该动力学分析可为舞台详细设计及优化创新提供依据及思路。

The movement process of the automatic folding stage was researched,and make a detailed dynamic analysis. Make dy- namics theory model for one group of stage, get the dynamics analytical formula of every mechanism, drawing power curve by MATLAB. Set up the appropriate kinematics model, and make dynamics simulation by ADAMS, compare the simulation results and the theoretical analysis value to prove the validity of the analysis. This dynamics analysis can provide theoretical basis for the detailed design of the stage, and provide ideas to optimization and innovation of the stage.
