中文摘要：

基于方位特征集的理论（POC）,对一平移二转动（1T-2R）并联机构进行了型综合;给出了一平移二转动输出并联机构拓扑结构设计的一般步骤和具体方法;基于该方法得到了一些一平移二转动输出并联机构,包括以前设计出的机型和部分新机型,并对它们进行了分析和分类。

英文摘要：

Using topological structure synthesis method Based on the POC set, the type synthesis ott - translational and 2 - rotation parallel mechanism is carried out. The general steps and concrete operation meth- ods of topological structure design of a 1 - translational and 2 - rotation parallel manipulator is given. Many kinds of mechanisms are obtained based on this approach, including some previously designed mechanisms and some new mechanisms, and these mechanisms are analyzed and classified.
