典型薄膜空间结构耦合动力学仿真分析

A dynamics simulation of the motion process of typical membrane space structures was made, and the dynamic response in the motion process of membrane space structures was solved by the finite element method to analyze the configuration transformation and the stress distribution in the deployable process. The motion process and the deployment stability of membrane space structures was studied by analyzing the system kinetic energy change of membrane space structures. The finite element models of typical membrane space structures, which included self-collision, rectangle deployment and inflatable balloon extension, were established by SAMCEF Mecano and then the numerical simulation based on coupling method was completed by defining the self-contact of membrane structures and the contact between membrane structures and flexible structures. The simulation results show that coupling dynamic simulation of typical membrane space structures is reliable by using SAMCEF Mecano. The dynamic properties are effected by different motion modes and the deployment stability is better when deployment rate is lower.
