【摘要】：为了提高柴油机活塞与缸套的装配精度,增大柴油机活塞缸套工作效率及使用寿命,解决目前柴油机活塞缸套装配随机匹配、人工修配等问题.按照船舶柴油机活塞缸套装配要求,对活塞缸套测量数据统一分装管理,结合装配精度范围,基于遗传算法的程序构建,设计面向装配过程的智能选配系统,使活塞缸套达到一一对应装配的目的,减少装配的随机误差以及累计误差对活塞缸套工作性能的影响,降低装配的返工率及人工修配带来的装配周期延长的问题.并以某机型柴油机的一组活塞缸套为例进行试验验证,获得了整体最优匹配结果.
[Abstract]:In order to improve the assembly accuracy of diesel engine piston and cylinder liner, increase the working efficiency and service life of diesel engine piston cylinder liner, and solve the problem of random matching of diesel engine piston cylinder liner assembly. According to the assembly requirements of piston and cylinder liner of marine diesel engine, the measurement data of piston cylinder liner are divided and managed, combined with the assembly precision range, the program is constructed based on genetic algorithm. An intelligent matching system for assembly process is designed to make piston cylinder liner achieve one-to-one corresponding assembly. The random error of assembly and the effect of cumulative error on the working performance of piston cylinder liner are reduced. The problem of reducing the rework rate of assembly and prolonging the assembly cycle caused by manual repair is also discussed. An example of a group of piston liners of a diesel engine is given and the overall optimal matching results are obtained.
