摘要:模块化桁架机构其动力源系统由于需兼顾多自由度、最简原则、可扩展性和空间环境,需要在应用中进行优化设计。本文针对一种模块化的多自由度空间可展开桁架机构,分析了模块化机构特性,包括单模块机构自由度和多模块机构组合特性,具体介绍了动力源的设计过程和优化方法,基于动力学虚拟样机技术进行了有源动力源与无源动力源的参数匹配性优化设计,提高了模块化机构的展开动力学特性和稳定性,降低了对主动动力源的功率需求。

Abstract:Power source system of modular truss mechanism needs to be optimized in application for catering its multi-degree of freedom, minimalist principle, scalability, and space environment requirements. In this paper, the design process and optimization method of power source for a modular deployable truss mechanism with multi-degree of freedom is introduced. Based on dynamic virtual prototype technique, the optimization design of active power source and passive power source for acquiring matched parameters is performed. The results show that proposed method can improve the deployable dynamic characteristics and stability of modular mechanism and reduce the power demand of active power source.
Key words:modular;deployable mechanism;dynamics simulation;power source
