摘要
对可变几何桁架（ＶＧＴ）结构展开运动学和动力学进行了系统分析。基于约束方程得到了运动学分析的递推公式；并利用Ｄ＇Ａｌｅｍｂｅｒｔ原理推导了ＶＧＴ展开的动力学方程；这些公式和方程简洁并具有规律性，适于计算机编程计算，通过算例分析验证了方法的可行性。
Deployment kinematics and dynamics of Variable Geometry Truss(VGT) structures are analyzed systematically. The recursive formulae of kinematic analysis are presented by using con- straint equations. Employing the D'Alembert's principle in virtual work, the dynamic equations of deployable VGT are derived. All of these formulae and equations are of a computer-oriented form. A numerical example is given to show the validation of the analysis method.
