交叉轴柔性枢轴，由两个柔性梁在其中点交叉而成，已经在柔性机构中使用多年。然而，它们的载荷-挠度行为尚未被适当地建模，以允许容易地分析和合成包含它们的机制。本文使用非线性有限元分析的结果来研究这种行为。在分析的基础上，提出了两种模型的枢轴-一个简单的和一个更复杂的。模型的准确性证明了由聚丙烯和钢制成的枢轴的测量结果进行比较。
Cross-axis flexural pivots, formed by crossing two flexible beams at their midpoints, have been used in compliant mechanisms for many years. However, their load–deflection behavior has yet to be appropriately modeled to allow easy analysis and synthesis of mechanisms containing them. This paper uses results of non-linear finite element analysis to investigate this behavior. Based on the analysis, two models for the pivots are presented – one simple and one more complex. The accuracy of the models is demonstrated by comparing results to those measured for pivots made from polypropylene and steel.
