A computational method is developed to study the dynamics of lightweight deployable structures during the motion process without regard to damping. Theory and implementation strategy of the developed method are given in this study. As a case study, the motion process of a bar-joint structure and a ring array scissor-type structure was simulated under external dynamic loading. In order to verify the effectiveness of the method, the simulation results are compared with the results predicted by the authenticated multibody system dynamics and simulation program. It shows that the method is effective to dynamic analysis of deployable structures no matter the structures are rigid or elastic. Displacement, velocity, and acceleration for the entire deployable structures during the motion process can be computed, as well as strain if the deployable structure is elastic.

可展开结构动力分析的一种计算方法

开发了一种计算方法来研究轻质可展开结构在运动过程中的动力学，而无需考虑阻尼。给出了该方法的理论和实现策略。作为一个案例研究，模拟了杆-关节结构和环形阵列剪式结构在外部动态载荷下的运动过程。为了验证该方法的有效性，将仿真结果与通过验证的多体系统动力学和仿真程序预测的结果进行比较。结果表明，无论结构是刚性的还是弹性的，该方法对于动态分析可展开结构都是有效的。可以计算出整个可展开结构在运动过程中的位移，速度和加速度，
