Abstract: The complicate fluid-solid interactions exist in the process of filling and outleting of water for the chamber of launching-typed ship lift, which is a critical technological problem that needs related researches and engineering pratice. In view of the mechanical problems of the filling and outleting of the water for the Jinghong hydraulic ship lift chamber, the systematical prototype monitoring is conducted for the first time to study the loading-deformation characteristics of the ship chamber, the changing rules of the levelness of the chamber and the synchronizing shaft torque, the vibration response and noise of the chamber, and the slamming force and absorption force on the chamber bottom plate. Meanwhile, the influences of the running speed of the chamber is investigated. The measured results show that the maximum bending deformation of the ship chamber is about 2.7 cm, the longitudinal inclination of the vessel is less than 20 mm, the maximum torque variation is about 162 kN·m, and the vibration, noise and absorption force of the vessel are not large because of the significant changes in the side load of the ship chamber. For the filling and outleting ofthe water at different speeds, the variation rules of all the parameters are basically consistent. But the fluctuation of the parameters increases with the increase of the chamber speed. After water filling into the ship chamber, the situation of the ship lift is completely recovered to the state before outleting the water, and the process of the filling and outleting of the water for the chamber is very stable and convergent. The flash start moment to filling the water and the moment of the bottom plate breaking away from the water are the key point in the process. The measured results not only provide a basis for the safe operation of the Jinghong ship lift, but also provide technical references for the design of other similar ship lifts.
