| Abstract: | This article introduces the designing theory and the basic construction of the crane hoist test bed. Simplifying the test bed into ninefreedom hoist mechanic model, the article analyses, through computer simulation, the dynamic resporse of the crane hoist during the transition of startup or lowering stop. Moreover, the article elucidates the influence of various parameters on the dynamic response of the hoist- the damp of elastic coupling, stiffness, each turning inertia of hoist shaft, etc. |
