摘要：
In order to study the dynamic characteristics of a container crane's lifting transmission system under variable working conditions, a dynamic model of the lifting mechanism was established to simulate the lifting dynamic load. A translation-rotation coupling dynamic model was built with considering the time-vary mesh stiffness and support stiffness of every gear pair. The displacement response of every gear pair and vibration characteristics were obtained during acceleration, constant speed and deceleration stage, and mesh force at three stages were analyzed in frequency domain. The results showed that the lifting dynamic load cannot be ignored, and the changing trend of torsional vibration is identical to the lifting dynamic load. Meshing force spectrum at acceleration and deceleration stage has side-bands by the variation of velocity. © 2016, Editorial Department of Journal of Northeastern University. All right reserved.
