摘　　要：从振动学的角度出发,对牵引链强迫振动时的扰动频率、弹性波的传播速度、牵引链自由振动时的自振频率几个方面进行了分析和探讨,推导出了牵引链的共振速度及共振长度,为避免牵引链发生共振现象、减小刮板输送机牵引链的动负荷提供了必要的理论依据。From the vibration of the point of view, linked from the traction when the disturbance forced vibration frequencies, elastic wave transmission speed, traction chain free vibration when the natural frequency of several aspects was analysed and explorat, traction chain resonance speed and length of resonance were derived, as the drive chain to avoid resonance phenomenon, reducing the traction scraper conveyor chain of dynamic load to provide a necessary theoretical basis.
