摘　　要：串联周期机构存在失谐动态响应并具有独特性,基于多体系统动力学理论和方法,提出了失谐机构建模方法并建立串联机构动力学模型。建立了太阳能帆板展开机构模型,仿真了随机失谐量下的失谐动态响应。结果表明,串联周期机构广泛存在失谐动态响应现象,失谐动态响应在机构系统局部存在。The series periodic mechanism has mistuned dynamic response and peculiarity. The series mechanism model is set up based on theory and method of multi- body dynamics. The mistuned mechanism modeling method is proposed and mistuned dynamic responses of a normal series periodic mechanism such as solar panel deployable mechanism under the stochastic mistuning is simulated. The results show that mistuned dynamic responses are common in series periodic mechanism. While rigid series periodic mechanism has localization of mistuned dynamic responses.
