摘　　要：根据含复铰平面闭式运动链的基本参数 ,定义了度谱、构件谱和复铰谱。同时考虑运动链中多副杆的连接关系 ,提出了一种新的运动链拓扑不变量———多副杆连接谱。在此基础上提出了含复铰平面运动链的谱分类方法 ,并给出了相应的算法。研究表明 ,这种分类方法具有计算简单、直观、便于计算机处理等特点。将这种分类方法应用在型综合中 ,可以有效地减少同构判断的计算工作量。The spectrums of degree,structural component and multiple hinges are defined according to the basic parameters of planar closed kinematic chain with multiple hinges.At the same time,by considering the connecting relation of multiple auxiliary bar in kinematic chain,a kind of new topological unvariable of kinematic chain--connecting spectrum of multiple auxiliary bar was advanced.The spectrum classification method for planar kinematic chain with multiple hinges was put forward by taking this as a base,and the relevant algorithm was presented.The research states clearly that this kind of classification method possesses characteristics of simple computation,direct visualization and convenient processing by computers.The amount of work for isostructural judgement may be reduced effectively when this kind of classification method is being applied to type synthesis.
