| 摘 要： | 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.

| Abstract: | Combined compliant structures were classified and the conditions of non-linear deflection of the flexible beam in a combined compliant structure were given on the basis of the effect of structural parameters on the deflection characteristic of combined compliant structures.In consideration of the variable cross-section and the non-linear deflection of a compliant structure,the deflection characteristic of the compliant structure was studied and a non-linear compliant-body model used for deflection analysis was established.Finally a combined compliant structure formed with flexible hinges and a flexible beam was designed and machined,and its deflection was analyzed by pseudo-body modelling,imitate-compliant body modelling and non-linear compliant-body modelling.Meantime,the deflection caused by electrostatic drive was tested.The results show that,the calculated data with the non-linear compliant-body model is most similar to the test results,proving the validity of this model and the analytical method. |
