Design And Dynamic Simulation Of Dry Dock Gate

During the past 30 years, especially in recent 10 years, the repair-manufacture ship industry in our country have a rapid development, and the repair-manufacture ship ability has been improved tremendously, in which the quantity of the large-size shipyard has increased continuously. Furthermore, a lot of large-size shipyards will be constructed in the coming years. The dry dock gate is the key equipment of the large-size shipyard, which influences the total function of the entire shipyard if it is designed improperly. In order to improve the dry dock gate's design level, the paper introduced new design method.There are three key segments in the design of the dry dock gate, which have been studied in my paper: the research on the dry dock gate's structure design; the research on the dry dock gate's technology design; the research on dynamic characteristics the dry dock gate.(1) The design of the dry dock gate's structure is researched, which is discussed detailedly on base of finite element method.(2) The interrelation and interaction of the dry dock gate's parameters in the technology design have been studied theoretically and, the calculation formulas about the volume of the fixed cabin and the operation cabin have been established which are based on the retail research and practical experience.(3) The paper had developed technology design software for the dry dock gate, provided to the designer with good interfaces, and introduced the operation method of the software through the concrete instance which has verified the practical value of the software.(4) In the paper, the uprising-downfall movement characteristics of the dry dock gate are researched by ADAMS. Furthermore, the uprising-downfall simulation curves and the uprising-downfall angle velocity curves are drew while the dry dock gate is at different water levels. The simulated results coincide with the test results very well. It indicates the accuracy of the mathematic model and the calculation method and the credibility of the simulated results.
