| With the rapid development of domestic shipbuilding industry,shipbuilding technologyis also changing with each passing day.In this paper,the half suspended double rudder button balance rudder and suspension balance rudder which are commonly used in large ships of over 50000 tons are taken as the research objects.By optimizing the installation process of some components,the construction period is shortened,the production resources are reasonably allocated,and the difficulties and problems encountered in the installation process of rudder system components are researched by using innovative methods.In order to shorten the construction period of rudder system assembly installation process optimization research,the first step is to record the installation process of rudder system,and then analyze and research the construction period.In the further research,the key components in each area of the rudder system are constructed in advance,so that the construction period of each area of the rudder system overlaps,thus reducing the overall construction period of the rudder system.By researching the installation process optimization of key components of rudder system,the corresponding process optimization scheme is determined,and the feasibility of the scheme is analyzed.In the research of promoting the reasonable allocation of production resources,firstly,the production resources in the installation process of rudder system are analyzed,and the unreasonable optimization points of resource allocation are found.Research the installation process of rudder system components corresponding to the optimization point,put forward the process optimization scheme,and analyze the feasibility of the scheme.Finally,the installation process optimization scheme of the above rudder system components is integrated into the rudder system installation process.In the research,it is found that in the process of berth construction of large ships with balance rudder suspended,because the existing rudder stock hoisting technology can not effectively control the attitude of rudder stock,in the process of the rudder stock hoisting into the rudder shaft barrel,the bottom of the rudder stock and the inner wall of the rudder shaft barrel are damaged by collision and friction.In this research,TRIZ tools and methods are used to propose a variety of optimization schemes,and the optimization scheme is selected and studied.Finally,the lifting technology of rudder stock berth is optimized.In this research,by optimizing the installation process of rudder carrier seat,steering gear seat and steering gear,the installation period of rudder system is shortened by 4 days,and the welding resources are rationally allocated.In the research of rudder stock hoisting based on TRIZ,a feasible process optimization scheme is obtained by making full use of TRIZ tools.In the research process,it is found that the improvement of ship building level,machining level and construction personnel’s technical level can provide space and conditions for the optimization of various construction processes in ship building;TRIZ innovation method is very effective for solving problems in the engineering field,which should be popularized to more construction technicians to master and use,and more key innovation technologies will emerge. |
