Abstract

Compliant mechanisms have increasing popularity. However, very few studies are available on transmission characteristics of compliant mechanisms in the literature. For conventional rigid-body mechanisms, the transmission angle is used to define motion quality. On contrary, the classic transmission angle formula cannot easily be employed for compliant mechanisms, unlike rigid-body mechanisms. This paper, a generalized equation that defines the transmission angle of all types of compliant four-bar mechanisms is introduced. For all configurations of partially compliant four-bar mechanisms, the formula is altered. Four theorems in some special cases are devised. Deviation of the transmission angle of a fully compliant four-bar mechanism from its rigid-body counterpart is discussed. Finally, a prototype is built and the theoretical approaches are compared with experimental results. To the best of our knowledge, this is the first study on the transmission angle of a compliant four-bar mechanism.

柔性四杆机构的传动角

兼容机制越来越受欢迎。然而，文献中关于柔顺机构传动特性的研究很少。对于传统的刚体机构，传动角是用来定义运动质量的。相反，与刚体机构不同，经典的传动角公式不容易用于柔性机构。本文给出了定义各种柔性四杆机构传动角的广义方程。对于部分柔性四杆机构的所有构型，公式被改变。在一些特殊情况下，提出了四个定理。讨论了全柔性四杆机构与刚体机构的传动角偏差。最后，建立了一个原型，并将理论方法与实验结果进行了比较。据我们所知，这是第一次研究的传动角度的一个顺从的四杆机构。
