The invention discloses a hydraulic ship lift ship reception chamber longitudinal anti-overturning theoretical analysis method. The method is based on a mechanical analysis method and a rigid body motion theory, and provides a hydraulic ship lift ship reception chamber with anti-overturning stability. The invention discloses a dynamic theory analysis method and system stability judgment conditions. When the synchronous system works independently and the guiding system works independently, the longitudinal anti-overturning characteristic of the ship reception chamber is static; Dynamic theoretical analysis research, the influence factors of the longitudinal anti-overturning characteristics of the synchronous system and the guide system are analyzed; It is explained that a synchronous systemgap value and a gap value between a guide wheel and a guide rail are important factors influencing the longitudinal anti-overturning characteristic of a system when the synchronous system and a guidesystem work independently, the influence of the existence of dynamic water overturning moment on the longitudinal inclination amount of a ship reception chamber is discussed, and the longitudinal anti-overturning mechanism of the ship reception chamber is disclosed. Scientific and reasonable basis and reference are provided for the longitudinal anti-overturning design of the ship reception chamber of the hydraulic ship elevator.
