Abstract: Based on the state-space approach, the conceptual design procedure of series mechanical system was proposed by applying the operations of dual-vector addition and matrix multiplication. The required scheme represented by the State Matrix (SM) allowed a given specification to be decomposed into a sequence of sub-SMs, and attempted to match each sub-SM with one or more stored basic units. Thus, the mathematical model for the design procedure was set up. Then the knowledge base system was established to store the characteristic information of the basic units. The data structures, the decomposing and the synthesis algorithm were also presented according to the established mathematical models and the knowledge base system. At last, a design example was given to show its effectiveness of the design procedure.
