The invention discloses an optimization method for a pulsation assembly line of a small-bypass-ratio aero-engine. The optimization method comprises the steps of optimizing of the assembly process flow, determining of the pulsation rhythm, determining of pulsation stations, determining of a product circulation mode between the stations, configuring of station resources, optimizing of process layout and conducting of pilot operation. According to the method, an original 'big rice bowl' mode of multi-person collective operation is broken, the number of workers at each station is greatly reduced, fine management and operation of each station are realized, the phenomenon of 'lost work' is completely eradicated, and the labor utilization rate is increased; the procedure content of each station is simplified, procedure division is clearer, the quality responsibility main body is clear, the requirement on the skill level of the workers is reduced, the operation proficiency of the workers can be greatly improved as time goes by, and the assembling consistency is improved; reform of engine assembling from a discrete mode to a production line mode is achieved, and the field management level, the assembly efficiency and the assembly quality are improved.
本发明公开了一种小涵道比航空发动机脉动装配线的优化方法,包括优化装配工艺流水、确定脉动节拍、确定脉动工位、确定工位间产品流转方式、配置工位资源、优化工艺布局和试点运行。本发明打破了原有的多人集体作业的“大锅饭”模式,各工位的工人数量大幅减少,实现了各工位的精细化管理和作业,杜绝了“窝工”现象,提升了人工利用率;简化了各工位的工序内容,工序分工更加明确,质量责任主体清晰,降低了对工人技能水平的要求,随着时间推移工人操作熟练度会大幅提升,提升了装配的一致性;实现了发动机装配由“离散模式”向“生产线模式”的改革,提升了现场管理水平、装配效率和装配质量。
