Mechanism and Variation Characteristics of Longitudinal Tilt of Ship Chamber of Hydro-Floating Ship Lift (HFSL)

Abstract

AbstractThe mounting clearance and deformation of the mechanical synchronization system of the HFSL directly affects the attitude of ship chamber, especially the longitudinal tilt of the ship chamber. In this paper, a generalized model is established to derive the analytical solution of the longitudinal tilt of the ship chamber according to the kinetic equations and differential equation theory of the rigid body with fixed axis rotation, and to reveal the mechanism of the longitudinal tilt of the ship chamber. According to the moment balance equation, the design conditions of the synchronous shaft rigidity of the HFSL are obtained. In addition, a mathematical model is established to simulate the change process of the longitudinal tilt of the ship chamber and analyze its variation characteristics.
