单自由度远程运动中心机构的型综合是研究多自由度远程运动中心机构的前提。由于现有的RCM机制种类不多，有必要寻找一种有效的方法来创建更多新的RCM机制。本文首先对现有的单自由度RCM机构进行了分类，然后基于平面虚中心（VC）机构的概念，提出了两种单自由度RCM机构的类型综合方法。一种情况是由两个平面VC机构组合而成的单自由度并联或串并联RCM机构;另一种情况是将VC机构扩展为串并联RCM机构。提供了相应的混凝土样品，其中一些是新类型。
Type synthesis of 1-DOF remote center of motion (RCM) mechanisms is the preliminary for research on many multi-DOF RCM mechanisms. Since types of existing RCM mechanisms are few, it is necessary to find an efficient way to create more new RCM mechanisms. In this paper, existing 1-DOF RCM mechanisms are first classified, then base on a proposed concept of the planar virtual center (VC) mechanism, which is a more generalized concept than a RCM mechanism, two approaches of type synthesis for 1-DOF RCM mechanisms are addressed. One case is that a 1-DOF parallel or serial–parallel RCM mechanism can be constructed by assembling two planar VC mechanisms; the other case, a VC mechanism can be expanded to a serial–parallel RCM mechanism. Concrete samples are provided accordingly, some of which are new types.
