Three Dimensional Finite Element Simulation Analysis Of Ship Lock Chamber Structure

This paper describes the analytic method of internal force of ship lock structure and the principle of finite element,method and process. There is a introduction about the main module of finite element analytic software,analytic mold and flowof analyse. Besides this paper takes the project of Fengyi, Jailing River, Sichuan Province, and makes an internal force analysis on its lower part of lock head by using analytic method and finite element method. As to the limitation of the traditional design of ship lock, we can establish a model to match the finite element analysis, account the internal force distribution of the three dimensions model. Full consideration about the effect between the ship lock and the around soil (rock) and also the situation of load from the lock wall which arrive to variational water level after filling back. According to the ways of accounting for the ship lock under 5 different situation, we can find the most disadvantageous situation., and we can analysis the reason and find out the way to solve the problem. Meanwhile, we discuss the structural safety and the factor to effect the stability of the ship lock from the aspect of finite element analysis and find the simplified account way to consider the effective factor. The following aspects are main to discuss during this paper:1. Founding the load of the lock from different five situations according to analytic method and get the result of internal force by combining the loads. From this, we can find the most disadvantage situation and test the stability by using the criterions;2. Using Abaqus finite element software to built the mold of three dimensions model of lock to simulate the effect between instruction of main body and the around soil (rock), then adjust the parameter and get the results according calculation;3. Compare and analyses the results from finite element and analytic method;4. During the project, we unite the technical way of spot research,theory analysis and date accounting, unite the design party,construction party and scientific research institutions to have a deep research on the Mechanical properties of ship lock.
