船体零部件补偿量的计算方法研究

船体建造精度控制是当代造船生产的关键技术之一,也是现代化造船科学管理的重要组成部分,其目的是最大限度地减少建造过程中的现场重复和修正作业量,缩短建造周期,降低造船成本.从船体建造精度控制的技术层面上看,如何能合理准确地给出船体零部件的补偿量,是船体建造精度控制方法需要研究的重要课题之一.船体零部件加工尺寸补偿就是在各零部件的基本尺寸上增加一个确定的量,以代替其工艺余量.文中开发了船体零部件加工测量数据库,应用统计质量控制理论建立了船体零部件加工补偿量数据统计的计算方法,应用尺寸链理论研究了船体零部件公差补偿量的计算方法.

A method for computing compensating amounts for ship hull parts

Precision control in ship production is one of the most important technologies in modern shipbuilding.And it is also an important constituent of modern scientific management of shipbuilding,which aims to reduce the workload for repetitive modifications of components,shorten the shipbuilding period,and lower costs.In view of this precision control in building a ship's hull,it is of great importance to know how to calculate appropriate compensation amounts.This paper mainly studies key technologies for determining appropriate compensation amounts for ship hull parts.In the paper,a database is constructed for the measurement of hull part machining.A computing method is developed for determining compensation amounts based on variability in hull part machining in accordance with statistical quality control theory.This approach to tolerance compensation amounts has been developed according to the dimension chain principle.
