摘　　要：为了在机构再生设计当中更齐全地列举杆型类配方案,提出了最多副杆的确定方法。假设除二副杆之外,只有一个最多副杆。根据总杆数和总副数可得出该最多副杆的运动副元素数。然后基于结构不退化原则,得出该数的限制公式,并通过逐次减1进行修正。最后,根据总杆数和各杆型的运动副元素数穷举出各杆型类配方案。对于十杆十三副运动链,该确定方法比通常方法多列举出两个方案;对于十三杆十六副运动链,多列举出4个方案。所以基于文中提出的最多副杆确定方法,可更加齐全地列举杆型类配方案。In order to exhaust the rod style classification and distribution plan（RSCDP） more completely in mechanism regeneration design,the method of deciding the rod with maximum number of pairs is proposed.Supposing that there is one rod with maximum number of pairs except for the rods with two pairs,the maximum number can be expressed based on the total number of rods and pairs.Then,based on the principle of no structure degradation,the restriction formula of the maximum number is deduced and corrected by subtracting one by one.At last,the RSCDPs are exhausted according to the maximum number,total rods number,total pair number and pair number on each kind of rods.For the 10 rods 13 pairs chain and 13 rods 16 pairs chain,9 and 13 RSCDPs are exhausted respectively be the proposed method.by reducing in steps of 1.two more plans can be exhausted by comparing this method with commonly used method.Therefore,the RSCDPs can be exhausted completely with the proposed method.
