摘要: 對柔性鉸鏈與桿組成的組合柔性結構的結構特征進行了研究,認為柔性鉸鏈與桿二者的厚度比、長度比是影響組合柔性結構變形特性的兩個特征參數.以一組不同結構尺寸的組合柔性結構為例,分別采用有限元法與偽剛體模型法對其變形進行對比,分析了組合柔性結構的厚度比、長度比對其變形特性的影響;根據特征參數不同取值對組合柔性結構變形特性的影響結果,對組合柔性結構進行了分類.

Abstract: 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.
