| 摘 要： | 介绍了一种空间新型少自由度三平移并联机构,该新型三平移并联机构是以-P-R-R-R-R-为支路结构。提出一种利用轴线相互垂直的转动副代替传统意义上的万向节的思想,即新颖柔性转动副。利用Pro/E对机构进行建模,通过MECHANISM/Pro模块导入ADAMS/View模块中进行仿真。分别在机构的3个移动支链上施加运动,通过计算机模拟,得到动平台的运动轨迹和角速度随时间变化的关系,表明该柔性机构在一定运动范围及频率下,引用无间隙的柔性关节,避免了因普通运动副间隙而造成的运动失真。

| Abstract: | A novel parallel mechanism was introduced,which can perform three-dimensional translation.This mechanism had three P-R-R-R-R chains;the paper provided a new idea,which uses the mutual vertical revolute pairs to replace the traditional universal joint.First is to use Pro/E to build the virtual prototype.Secondly,use the software MECHANISM/Pro to import the virtual prototype to ADAMS/view.Finally,the moving condition of movable platform,such as movement track and angular velocity,was obtained through driving ... |
