针对Ω形可展开弯杆多参数耦合、设计困难的问题,对Ω形可展开弯杆的屈曲载荷、两侧刚度差异特点等进行了仿真分析,拟合了计算公式;并研制了样机,进行了试验测试,仿真结果和试验结果匹配性良好.研究内容为多参数Ω形可展开弯杆的快速设计和推广使用积累了技术.%In this paper, the problem of multi-parameter coupling and design difficulty of deployableΩ-shape curved bar was studied. The buckling loads and rigidity difference of the deployable Ω-shape curved bar were simulated and the fitting formulas were obtained. The prototype testing showed that the experimental results and the simulation results matched well. The research lays a good foundation for the rapid design and promotion of deployable Ω-shape curved bars.
