船舶动力装置模块化建造工艺设计及精度分配

Process planning and accuracy distribution of marine power plant modularization

[目的]模块化造船有利于缩短设计建造周期、降低生产成本、提高产品质量,但给船舶建造能力提出了较高的要求,尤其是动力装置的安装。由于其具有对接安装精度高、设备安装尺寸链长、安装对接接口多等特点,较易产生由于对接安装设备间偏差大而无法对接安装,以及对接安装精度差导致的设备运行异常振动噪声等问题。为有效化解上述建造工艺设计及精度分配问题,[方法]在现有国内船舶建造能力的基础上,运用数值分析方法,开展动力装置模块化建造精度分配计算分析。[结果]数值计算分析表明,各对接安装环节精度分配合理可行,相关调节余量设置满足船舶建造要求。[结论]上述数值分析方法可用于指导船舶动力装置模块化建造。

[Objectives]Modular shipbuilding can shorten the cycle of design and construction,lower production costs and improve the quality of products,but higher shipbuilding capabilities are required,especially for the installation of power plants. Because of such characteristics of modular shipbuilding as the high precision of docking links,long size equipment installation chain and quantitative docking interfaces,docking installation is very difficult due to high docking deviation and low accuracy of dockinginstallation,leading to the abnormal vibration of equipment. In order to solve this problem,[Methods]on the basis of domestic shipbuilding capability,numerical calculation methods are used to analyze the accuracy distribution of modular installation.[Results]The results show that the accuracy distribution of different docking links is reasonable and feasible,and the setting of adjusting allowance matches the requirements of shipbuilding. [Conclusions]This method provides a reference for the modular construction of marine power plants.
