摘要

为设计一种高精度、结构简单的大变形柔性铰链，提高并联平台的运动精度和零件使用寿命，本文提出了一种Y型柔性铰链。首先，借助ANSYS和ADAMS进行柔性铰链的回转中心、安装方式和行程要求的分析研究。接着，利用数控机床进行柔性铰链的加工制作。然后，利用光学坐标测量仪OPTOTRAK进行柔性铰链的轴漂测量实验。最后，进行了转动副并联平台、单片簧柔性铰链并联平台和Y型柔性铰链并联平台的圆轨迹实验。实验结果表明：Y型柔性铰链回转误差最大值为0.5962mm，Y型柔性铰链并联平台圆轨迹的误差最大值比转动副并联平台减小了42.7%。Y型柔性铰链可以很好地替换并联平台中的转动副，提高并联平台运动精度。

Abstract

In order to design a large deformation of flexure hinge with high precision and simple structure and to promote the motion precision of parallel platform and the life of elements

a Y-type flexure hinge was proposed in the article. Firstly

made analysis and study of the rotation center

installation method and stroke requirements of flexure hinge by application of ANSYS and ADAMS. Secondly

processed the flexure hinge by using CNC machine. Thirdly

measured the axis drift of flexure hinge by using the 3D optical coordinate measuring instrument OPTOTRAK. Finally

conducted the circle trajectory experiments of parallel platform with kinematic pairs

leaf spring flexible hinge and Y type flexible hinge. The results show that the maximum rotation error of Y type flexure hinge is 0.596 2 mm and the maximum error of circle trajectory on the parallel platform provided with Y type flexible hinge decreased by 42.7% as compared with on the parallel platform provided with kinematic pairs

which means Y type flexure hinge can substitute the kinematic pairs in the parallel platform and able to promote the motion precision of the parallel platform.
