The invention relates to the technical field of ship lifts, in particular to a physical model test device and method for a vertical ship lift, and the device comprises a horizontal sliding table, a concrete tower column model, an active lifting mechanical transmission mechanism, a ship reception chamber model, a ship body model, and a vibration excitation device. The concrete tower column model comprises two concrete tower columns oppositely erected on the horizontal sliding table, and a lifting channel for containing the ship reception chamber model is formed between the two concrete tower columns; and the ship lift chamber model is arranged at the top end of the concrete tower column model, is in transmission connection with the ship lift chamber model and is used for driving the ship lift chamber model to lift along the lifting channel. The method comprises the following steps: simulating five normal conditions of a normal synchronous lifting operation condition, a non-synchronous trim operation condition, a locking state longitudinal earthquake operation condition, a normal synchronous lifting and longitudinal earthquake coupling operation condition and a non-synchronous trim operation and longitudinal earthquake coupling operation condition of a traditional steel wire rope winch type vertical ship lift; and the dynamic response characteristic of the multi-body coupling system under abnormal and extreme operation conditions is realized.
Description
technical field [0001] The invention relates to the technical field of ship lifts, in particular to a physical model test device and method for a vertical ship lift. Background technique [0002] The wire rope winch type vertical ship lift is a large and complex system including concrete towers, mechanical transmission, ship bearing compartment, fluid and hull in the compartment. At present, the 200m-class high-lift hoisting vertical ship lift that is being pre-researched in the lower reaches of the Jinsha River in China is the hoisting vertical ship lift with the largest single-stage hoisting height proposed to be built in the world so far. According to the navigation requirements, the ship lift will lift the 17,200t ship bearing box, the water body in the box and the 3,000t class ship by nearly 200m in elevation, and its operation safety must not be compromised. [0003] At present, domestic and foreign studies on the stability of the pitching motion of the ship's vessel ...
