基于GO法的火炮驻退机可靠性分析

Hydraulic Buffer Reliability of Gun Based on GO Methods

对基于GO法的故障规律研究过程进行了描述。在假设驻退机其它部分(除驻退筒、驻退液以及温度)均不发生故障的情况下,首先建立GO图,根据操作符代表的单元特性,确定操作符的状态概率数据,然后通过定量GO运算得到各信号流的状态概率,最终可得到系统的状态概率运算结果。该方法分析方便,尤其适用于考虑环境因素和时序变化的系统可靠性分析。

Research process based on GO method is described for studying failure rule. Suppose parts of gun except recoil brake （except recoil canister, recoil fluid and temperature） in normal condition. First, GO chart is built in which state probability data of operation character is acquired according to unit characteristics. And then through quantificational GO calculation, state probability of each signal flow is gotten. Finally, state probability of whole system is calculated. The method is convenient to use, especially in considering environment elements and timing sequence conditions.
