摘要
平面机构中虚约束的存在,给制造加工和机构运动分析带来了诸多不便.从虚约束的定义出发,分析了机构中虚约束存在的几种形式和虚约束成立的充分必要条件,给出了虚约束的判定步骤和机构中虚约束数的计算方法.
Virtual restraint in planar mechanism brings about many problems to machining and mechanism movement analysis. According to definition of virtual restraint, this paper analyses several forms and neces- sary and sufficient conditions of the existence of virtual restraints in mechanism, and presents the procedures for the judgment of virtual restraint and the calculating methods for the number of virtual restraints.
