摘　　要：由连续法得到满足刚体导引综合要求的齿轮四杆机构,利用该机构连架杆摆角函数的谐波成分(由快速傅立叶变换得到),通过模糊识别的方法,从已建立的齿轮四杆机构的连架杆摆角函数谐波特征参数的"数值图谱库"中找到更多组满足设计要求的机构。文中给出的算例验证表明,该方法解决了有限点位连杆机构尺度综合的多解问题,为连杆机构的尺度综合研究拓宽了思路。Geared Four-Bar Linkages meeting the requirement of synthesis of rigid-body guidance is obtained by continuation method.According to the harmonic components of Side Link Swing-Angle Function (obtained with fast fourier transfer method),more mechanisms which meet the requirement of design can be found by using the method of fuzzy identification from numerical atlases of Side Link Swing-Angle Function's harmonic characteristic parameters of established Geared Four-Bar Linkages.The numerical examples given in the paper have proved that by this way many linkages according to the demand of dimensional synthesis of limited point are found,broadening the scope of research in dimensional synthesis for linkages.
