The Dynamic Analysis of Gantry Crane Girder under Lifting Process
Abstract:
In order to get the displacement response curve of the Gantry Crane Girder under three stage of lifting process, the vibration differential equation and displacement response expression were deduced, combining with the actual case, the displacement response expression and displacement response curve were deduced in the load duration time 0.8 s and 0.2 s. The results show that: the lifting process is an important factor affecting the structural vibration; Displacement peak and load duration time are inversely proportional; Increase the load duration time can reduce the vibration of the structure.
