Method for determining ship lock health monitoring key components

Abstract

The invention discloses a method for determining a ship lock health monitoring key part. The method comprises the following steps: S1, constructing a ship lock structure decomposition system; S2, establishing a ship lock fault event database; S3, analyzing a fault part by utilizing the fault event database; S4, analyzing a fault mode, an influence and a hazard degree; and S5, determining a key part of health monitoring based on an analysis result. According to the method, important functional components are determined as monitoring objects according to the hazard degree, the occurrence probability and the generated comprehensive influence of various possible failure modes of the ship lock, the scientific rationality of the ship lock health monitoring system design is improved, the failureoccurrence probability is reduced, and the method can be widely applied to the technical field of ship lock construction and maintenance management.

Description

technical field [0001] The invention belongs to the technical field of water transportation engineering, and mainly relates to a method for determining key components of ship lock health monitoring. Background technique [0002] As a key infrastructure on the waterway transportation channel of bulk cargo, ship locks will cause a large number of ships to be stranded and cargoes to be delayed if they cannot operate normally, and even endanger the production plan of enterprises. There are more than 1,000 navigable ship locks in my country. With the construction of high-grade waterways, a large number of ship locks still need to be built. [0003] In order to ensure the safety of the ship lock, the preventive maintenance mode based on regular maintenance is currently adopted, combined with post-event maintenance to ensure the normal operation of the system. Most of the regular maintenance of ship locks follows the historical experience. During the overhaul, it is common to repa...

Problems solved by technology

Therefore, it is difficult to accurately judge the health status of the entire ship lock system through the monitoring of a single subsystem or component. It is an urgent need for the design and maintenance management of the ship lock health monitoring system to comprehensively determine the health monitoring objects by comprehensively considering the reliability and economy of the system.
