基于柔性铰链的杠杆-平衡机构的运动特性分析与参数设计
Kinematics Analysis and Parameter Design of Leverage Balancing Mechanism Based on Flexible Hinges
摘要
Abstract
Leverage balance mechanism based on flexible hinges for small force measurement with mN order resolu⁃tion and N order range is described in this paper,and the motion model is derived. Finite element method(FEM, ANASYS)is used to validate the mathematical model. According to the results of both mathematical model and the FEM analysis,a conclusion that the displacement of the test force generated can be increased by reducing the stiff⁃ness of the flexible hinges and increasing the length of the parallel four-rod mechanism is obtained. Required lever⁃age ratio and motion model can be obtained by reasonably choosing the leverage length of the hinge pivot on both sides. Thus a theoretical basis for the design of the mechanism is provided.关键词
