摘　　要：平面曲柄滑块机构近似导向综合数值解法设计参数多(7个),求解难度大,且计算效率低下。为解决这一问题,提出了平面曲柄滑块机构导向综合的方法:将其拆分为两个双杆组,分别进行综合,并将综合结果组合以得到符合要求的平面机构,减少了单个方程组的设计参数,大大降低了求解难度,提高了计算速度。最后,推导出了两个双杆组的综合方程组,并给出了具体实例,使用实数连续法求解,得到了3个能满足设计要求的机构,实现了方案选优。Approximate synthesis of crank-slider mechanism for guidance can be solved by numerical method,but it has low efficiency because of too many parameters（seven）.In order to solve this problem,an efficient solution was presented.The linkage was decomposed into two parts,and each of them was synthesized respectively.The crank-slider mechanism was obtained by combining the solutions.The number of parameters was decreased,and the efficiency was enhanced.Two equations of synthesis were deduced.An example was provided and three suitable linkages were obtained by using real continuation method.Results show that the optimal design of the planar mechanism could be choiced further.
