民机机头系统脉动装配生产线规划与车间布局设计

Pulsating Assembly Line Planning and Workshop Layout Design of Civil Aircraft Nose System

脉动装配生产线是一种新型的飞机装配组织模式,能够有效缩短飞机装配周期,提高装配质量和效率。同时,飞机机头系统集成的任务模块化划分与脉动装配生产线以模块式方式设计装配线的思想契合,具备脉动装配的基本条件。为提高飞机机头系统集成效率,以某型号飞机机头系统为研究对象,通过分析其模块化交付的具体装配流程,以装配顺序约束为主要依据划分站位、确定脉动节拍并借助ECRS(Eliminate–combine–rearrange–simplify)分析法进行优化,基于系统布置设计(Systematic layout planning,SLP)方法提出机头脉动装配生产线车间布局设计的具体设想。最终给出的负载均衡的站位设定与合理物流的车间布局方案,为民机进一步开展各类机头系统脉动装配生产线研究提供支持。

Pulsating assembly line is a new aircraft assembly organization mode,which can effectively shorten the aircraft assembly cycle and improve the assembly quality and efficiency.At the same time,the task modularization division of aircraft nose system integration is in line with the idea of modular design of pulsating assembly line,which has the basic conditions of pulsating assembly.In order to improve the integration efficiency of aircraft nose system,this paper takes a certain type of aircraft nose system as the research object,analyzes the specific assembly process of modular delivery,divides stations and determines pulse takt time based on assembly sequence constraints,and optimizes it with the ECRS(Eliminate–combine–rearrange–simplify)analysis method.Based on the system layout design(SLP)method,the specific idea of workshop layout design of head pulsation assembly line is put forward.Finally,the load balanced station setting and reasonable logistics workshop layout scheme are given,which provide support for civil aircraft to further carry out the research on pulsating assembly lines of various nose systems.
