Abstract：For the deciding of rod with maximum pair number in the regenerative motion chain method, the theoretical computing formula was deduced. So the new deciding method of maximum number of pairs on rod is proposed. Supposing that one rod with maximum pair number hold all the pairs except for the pairs on the two-pair rod, this maximum pair number is gotten based on the total rod number and total pair number. Based on the least loop circuit number surrounding the rod with maximum pairs number and the principle of no structure degradation, the restriction formula of computing maximum pair number is gotten. The principle is that the pair number in a loop circuit should be no less than 4. After computing the maximum pair number, each plan of rod style plan classification and distribution can be exhausted based on the total rod number. Verified by several generalized kinematic chain, the proposed method can exhaust the plans more completely.
