对柔性铰链与杆组成的组合柔性结构的结构特征进行了研究,认为柔性铰链与杆二者的厚度比、长度比是影响组合柔性结构变形特性的两个特征参数.以一组不同结构尺寸的组合柔性结构为例,分别采用有限元法与伪刚体模型法对其变形进行对比,分析了组合柔性结构的厚度比、长度比对其变形特性的影响;根据特征参数不同取值对组合柔性结构变形特性的影响结果,对组合柔性结构进行了分类.
Structure characteristics of a combined compliant structure formed with a flexible hinge and a flexible beam are studied.The thickness ratio and the length ratio between the flexible hinge and the flexible beam are two characteristic parameters which influence deflection characteristics of the combined compliant structure.A group of combined compliant structures with different thickness ratios and length ratios are given,and their deflection is analyzed with the finite element method and the pseudo-body model,respectively.The influence of thickness ratio and length ratio on their deflection is discussed.Based on different values of the two characteristic parameters,the combined compliant structures are classified into different kinds.
