摘　　要：分析了一类齿轮五杆曲柄滑块机构的尺寸约束条件,利用复矢量理论和Fourier级数理论建立了机构连杆轨迹的数学模型,推导出计算机构实际尺寸和安装位置参数的数学公式,根据曲柄和连杆间传动比的不同分别建立了相应机构连杆转角算子谐波特征参数的数值图谱库。利用数值图谱法实现了齿轮五杆曲柄滑块机构连杆轨迹的尺度综合,综合算例证明了该方法的实用性和有效性。The dimensional constraint conditions of a kind of geared five-bar crank-slider mechanism （GFBCSM） were analyzed. Mathematic model of coupler path has been established based on complex vector theory and Fourier series theory. The mathematic equations for calculating actual dimensions of mechanism, coupler＇s point position and mechanism installation parameters were derived. Several numerical atlas databases of harmonic characteristics of coupler rotation-angle operators have been set up for transmission ratio i = - 1, ± 1/2, ± 1/3 between the crank and the coupler. Dimensional synthesis of coupler path of GFBCSM has been realized by using the numerical atlas method, and the given example showed that the method is efficient and feasible.
