毕业设计（论文）中文摘要JW 公 司 发 动 机 气 门 生 产 效 率 分 析 与 改 善研 究摘 要 ：在汽车产业繁荣发展的带动下，零部件企业的成长呈现迅猛之势，零部件的市场需求越来越大。JW 公司作为汽车零部件制造企业，主营业务是气门设计、生产与销售。本文应用生产线优化，生产系统改善的相关理论，在进行文献综述的基础上，针对 JW 公司机加工车间气门生产效率不高的问题，借助工业工程方法和工具，对车间生产线进行改善研究，研究发现了生产线上电镦工序机器设备落后、杆身检验工序作业方法不标准，并采取升级设备、合并工序、简化操作等方法对瓶颈工序进行改善，得到了工业工程对优化生产线，提高生产效率具有重要意义的结论。工业工程在 JW 公司的应用，为更多制造业开展生产线优化和效率改善提供了方向和启迪。关键词： 程序分析；人机作业；瓶颈；生产效率毕业设计（论文）外文摘要Title Analysis and improvement of engine valveproduction efficiency of JW company AbstractDriven by the prosperity and development of the automobile industry, the growth of parts enterprises is showing a rapid trend, and the market demand for parts is increasing. JW company as an automotive parts manufacturing enterprise, the main business is the engine valves. Based on the literature review, this paper applies the theory of production line optimization and production system improvement, directs at the low production efficiency of the valve production line of machining workshop, and studies the improvement of the workshop production line with the help of industrial engineering methods and tools. The study found that the equipment of the electrical processes on the production line are backward, the operation method of the rod-body inspection process is not standard, and the bottleneck process is improved by upgrading equipment, combining the operation and simplifying the operation. The conclusion of industrial engineering is of great significance to optimize the pr...
