根据组合柔性结构的结构参数对其变形特性的影响,对组合柔性结构进行了分类,并给出了组合柔性结构中柔性杆存在非线性变形的条件.考虑柔性结构的变截面特征和非线性变形的问题,对组合柔性结构的变形特性进行了分析,建立了变形求解的非线性柔性模型.最后设计并加工了一种柔性铰链-柔性杆组合结构,分别采用伪刚体模型、拟柔性模型和非线性柔性模型对其变形进行理论计算,同时采用静电驱动方式对组合柔性结构的变形进行测试.结果表明,非线性柔性模型的计算结果与实验测试结果最接近,证明了此模型和分析方法的有效性.
According to the influence of the structural parameters of the composite flexible structure on its deformation characteristics, the composite flexible structures are classified and the conditions for the nonlinear deformation of the flexible rods in the composite flexible structure are given.Considering the variable cross-section characteristics and the nonlinear deformation of the flexible structure The deformation characteristics of the composite flexible structure are analyzed and a nonlinear flexible model for solving the deformation is established.Finally, a flexible hinge-flexible composite structure is designed and fabricated, the pseudo-rigid body model, pseudo-flexible model and non-flexible model The linear flexible model was used to calculate the deformation and the electrostatic drive was used to test the deformation of the flexible structure. The results show that the nonlinear flexible model is the closest to the experimental results, which proves that the model and the analysis method are effective Sex.
