Deployable space structure has been widely used in the development of space exploration , research has also become a hot issue . This paper reviews the domestic and foreign space to expand the application status of the structure of the research significance of the Meridian Project farm extension rod and electronic extension rod . Sleeve space to expand the structure of the system design and kinematic analysis , and the collision contact stress in the stretching process dynamics simulation analysis . In-depth study of the structure to provide a valuable reference for the rocket-borne space to expand . First deployable space structure , the use of the UG software that stretched rod and electronic Meridian Project farms stretch rod for three-dimensional modeling , then discusses the many-body system dynamics theory foundation and virtual prototyping technology MSC.ADAMS software and commence the process kinematics simulation analysis , the results showed that the stretch rod can be commenced smoothly , but the deployment process , relative speed before the collision greater need checking . To this end, a the stretch rod finite element model , and dynamics simulation analysis . Four thickness dimensions compared that with the the stretch rod wall thickness increases , and can not effectively reduce the stress caused stretch rod collision process . The papers in the Comprehensive predecessors space to expand on the basis of the structure and dynamics simulation technology research , the main innovation lies in : the integrated application of CAD 3D design software , and multi- body dynamics simulation analysis software and finite element analysis software to co-simulation . Structure designed and developed to expand in space and try to practice the institutional and structural design method of harmonization . Provide a deployable space structure to the problem of computer-aided engineering ; replaced . Sleeve space to expand the deployment dynamics simulation of the structure , explicit finite element nonlinear transient dynamics a function of the contact force of the rigid body dynamics to analyze stress and check a collision course . The commencement of the collision process simulation makes sense to try and explore .
