对提高准流体安全系统交验合格率的攻关

Research on Improving the Qualification Rate of Quasi-fluid Safety System

针对某种准流体安全系统解保时间超差的问题,运用因果分析法研究发现,泄流孔结构是影响准流体安全系统解保时间的主要因素.对泄流孔结构尺寸进行的多次试验表明,在泄流孔外沿增设倒角可有效缩短安全系统解保时间.根据这一结论,指导10个批次约9万发产品的零件加工和部件装配,获得了顺利交验.解决了某型号引信多年生产交验过程中安全系统解保时间超差的问题.

Due to the poor warranty time of the quasi-fluid safety system,the causal analysis method is used todetermine the structure and size of the drain hole.Through analysis and research of the size of the drain hole and a large number of experiments,the regularity that increasing the chamfer structure on the outer edge of the drain hole can effectively shorten the warranty time of the safety system is summarized.And this guides the processing and assembly of parts for 10 batches of about 90,000 rounds of products,and submit them smoothly for inspection thereby to solve the problems of upper limit and out-of-tolerance of safety system release time in this model fuze's production practice for many years.
