Analysis vertical lifting tower structure base on FSI method

Abstract

   The vertical lifting tower is a new type of structure which ensure ship traffic requirements at height dams. The advantages of this structural form are simple structure, economic operation, and timesaving. However, during manufaturing, when the ship lift to a certain height, the cabin will tilt, shake and generate torque leading to overturning, causing serious consequences. Specailly, research on interaction between the water in the tower shaft and the tower structure, the water in the cabin and the structure which contain it under the impact factor of earthquakes is an important rule that directly determines the safe bearing capacity and normal use of the lifting tower structure. Base on FSI method
between solid and water, the article will analyze the relationship between the water depth in the tower shaft and the position of the lift cabin to reusults of vibrations, displacements and stresses of the vertical lifting tower structure under different operating conditions. Thereby warning of unfavorable locations of cabin lift ship during operation should be paid attention in the design calculation process
