叶型等腰梯形挠曲枢轴在柔顺机构的设计中具有重要的实用价值。分析这种支点的载荷-挠度行为对于研究由它们组成的机构是必不可少的。在分析单个特殊载荷叶片段的基础上,提出了一种拟刚体四杆模型。对于一些简单的应用,将四杆模型进一步简化为销-联接模型。通过与非线性有限元分析结果的比较,验证了这两种模型的准确性。最后,以侧翻铰链为例,应用这两种模型对其进行了分析。
A leaf-type isosceles-trapezoidal flexural pivot can be of great practical use for designing compliant mechanisms. The analysis of load-deflection behavior for such a pivot is essential to the study of the mechanisms that are comprised of them. Based on the analysis of a single special loaded leaf segment, a pseudo-rigid-body four-bar model is proposed. The four-bar model is further simplified to a pin-joint model for some simple applications. The accuracy of both models is demonstrated by comparing results to those of nonlinear finite element analysis. At last, the two models are applied to analyze the cartwheel hinge as an example.
