【摘要】 通过对连杆机构传动函数特性的分析,提出了以傅里叶级数作为插值函数、以机构等间距点作为插值结点,进而求出传动函数近似展开式的三角插值法;并以实例说明这种方法能够得出形式简洁、误差较小的传动函数近似展开式。将这种方法应用于连杆机构的运动分析中,可以有效地简化传动函数,有利于对其具有的运动、动力学特性进行更深入的研究。更多还原

【Abstract】 Through the analysis of transmission function for link mechanism with characteristics,it suggests that taking a Fourier series as an interpolation function and taking equal spaced points as interpolation nodes,in order to obtain the transmission function with approximation expansion.The examples analysis shows that this method is convenient and accurate.Applying this method applied to link mechanism motion analysis is useful to a more in-depth study about the movement and dynamics.更多还原
