摘要:

提出了一种简易实用的二平行导轨二滑块驱动在一侧的可变长平面并联机构,分析了该机构的结构特点,发现该机构具有大范围作业空间的优势。推导了该机构的运动学正反解计算公式,基于其运动学反解,仿真分析了该机构末端执行器满足各类直线、圆轨迹时,二滑块驱动的运动规律及特性,并在研制的实验样机上得到了验证。

Abstract:

An innovative, simple and practical planar parallel mechanism was presented,which was with two parallel axis and two slide-drivens on one side.Its structural characteristics and the advantages of large workspace were analyzed,and the positive and negative solutions were given. Based on its negative solution, the motion simulation and characteristics of the end effector of
the mechanism were carried out, when it produced all kinds of straight lines and circles. The results were validated on a experimental prototype.

Key words: parallel mechanism, kinematic analysis, kinematic synthesis, workspace analysis
