摘　　要：CFRP(Carbon-Fiber-Reinforced-Plastic)薄壁弹性杆可展机构当前在空间可展支撑机构领域应用广泛,关于其力学性能的研究和设计优化是当前研究的热点。本研究基于Abaqus有限元仿真软件,对厚度为0.8~0.9mm的CFRP薄壁弹性杆的收展过程进行了力学仿真模拟,得到了CFRP薄壁弹性杆在直径100mm的卷筒上达到指定弯曲状态时的应力分布结果,验证了CFRP薄壁弹性杆的强度并归纳总结了CFRP薄壁弹性杆弯曲时的应力分布规律。Carbon-fiber-reinforced-plastic Thin-walled Elastic Boom Deployment mechanism is currently widely used in the field of space deployable support mechanisms.Research on its mechanical properties and design optimization are current research hotspots.Based on the finite-element simulation software Abaqus,this study conducts a mechanical simulation on the unfolding process of the CFRP thin-walled elastic deployable boom with a thickness of 0.8~0.9mm,and obtains the stress distribution when the deployable boom reaches the specified bending state on a spool with a diameter of 100mm.As a result,the strength of the deployable boom is verified and the stress distribution law of the deployable boom in the bending state is summarized.
