摘　　要：通过对双曲柄滑块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、以机构特殊位置点作为插值结点,进而求出传动函数近似展开式的方法。同时,通过对实例的分析说明这种方法具有求解方便、精度高的特点。将这种方法应用于双曲柄滑块机构的运动分析中,有利于对其具有的运动特性以及动力学特性进行更深入的研究,并且,对其它连杆机构的分析也具有指导意义。In this paper, through the analysis of transmission function for dual-slider-crank mechanism with characteristics, it suggests taking a Fourier series as an interpolation function and taking special position points of the mechanism 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 to dual-slider-crank mechanism motion analysis is useful for a more in-depth study about its movement and dynamics. Besides, this approach also is instructive to the motion analysis of other mechanisms.
