摘要。柔性关节是柔性机构的重要组成部分。大多数已知的柔性关节总是在精度、刚度和行程等性能之间进行权衡,这严重影响了柔性机构的整体性能。提出了一种新的柔性关节——反对称双叶型等腰梯形柔性关节(ADLIF)。该关节由两个叶片型等腰梯形弯曲(LITF)构件以反对称形式构成。为了研究两种不同结构参数的ADLIFs的精度、刚度和行程等特性,以一个侧轮铰链为例进行了比较。此外,为了简化参数化模型,实现结构优化,建立了简单准确的ADLIF伪刚体(PRB)连接模型。结果表明,ADLIF在保持刚度和运动范围等其他特性的基础上,在精度上有了很大的提高。即使在旋转角度小于5度(5°)的情况下,ADLIF的精度也提高了16倍以上。因此,ADLIF可用于某些精密应用领域的车轮关节的替换。
Abstract. A flexure joint is an important component in flexure mechanisms. Most of well known flexure joints have always a trade-off among such performances as precision, stiffness, and stroke, which heavily affect the overall performances of flexure mechanisms. In this paper, a new flexure joint, named an anti-symmetric double leaf-type isosceles-trapezoidal flexure joint (ADLIF), is introduced. The joint is constructed by two leaf-type isosceles-trapezoidal flexure (LITF) building blocks in an anti-symmetrical form. In order to investigate such characteristics as precision, stiffness and stroke, two ADLIFs with different structural parameters are compared with a cartwheel hinge. In addition, a simple and accurate pseudo-rigid body (PRB) joint model of the ADLIF is formulated to simplify the parametric model and achieve the structural optimization. The results show that the ADLIF can gain a great improvement in precision as well as maintain other characteristics such as stiffness and ranges of motion similar. Even the ADLIF gets more than 16 times improvement in precision in the case that the rotational angle is less than five degrees (5°). The ADLIF can thus be used for the replacement of the cartwheel joint in some precision application fields.
