摘要
针对一类折叠式桁架结构系统 ,导出了其展收运动动力学模型 ,提供了求解相应的非线性微分———代数方程组的方法。桁架系统展收运动仿真算例表明 ,由于所建立的动力学模型规模较小 ,所提供的求解方法不需迭代 ,因而数字仿真所需的计算时间很少 。
A dynamic model for a kind of deployable truss systems is derived. The method for solving the derived nonlinear differential-algebraic equation system is provided. An example is given to simulate the deployment of a typical truss system. It is shown that the derived model and the provided method for solving the dynamic equations are efficient for the truss system deployment simulation. The difficulty encountered in applying the commercial dynamic software can be avoided.
