摘要
为了提高火炮方向机齿轮传动误差(GTESMG)的分析效率并考虑工程设计可行性,提出了一种改进的多分布协作响应面算法(MDCRSA)。该算法从概率的角度出发,综合考虑静态影响因素和动态影响因素,结合响应面法和蒙特卡罗法,评估系统可靠性。将该算法应用到实际项目中估算GTESMG的可靠性,结果显示:当GTESMG的设计值为10′时,估算的可靠度为0.990,基本上满足GTESMG的设计和工程需要。同时通过与传统估计可靠性方法的比较,可以看出MDCRSA算法具有较高的计算效率及精度,并且这种优势随着计算次数的增加而更加明显。MDCRSA算法不仅可以评估GTESMG可靠性,还可预测火炮其他部件的可靠性。
To more accurately show the gear transmission errors of the steering mechanism of the gun (GTESMG) ,reliability analysis of the GTESMG was carried out from a probabilistic perspective by considering multiple factors and dynamic loads. According to GTESMG's practical applications and theoretical researches, MDCRSA were proposed and the mathematical model of this algorithm was es- tablished based on a quadratic function, the detail description of the algorithm was given herein. Then an illustrative real project was used to validate the algorithm in some aspects. The simulation results show that when the design value of GTESMG is as 10' ,the reliability is as 0.990,it may meet the re- quirements of a steering mechanism of gun. Through the comparisons with traditional five analysis methods which were used to evaluate the reliability of gun, the results show that MDCRSA has higher precision and higher efficiency in the reliability analysis of GTESMG. These strengths are likely to be- come more prominent with increasing simulation times. This research provides an effective and excel- lent method for the reliability analysis of GTESMG, moreover, the MDCRSA offers a useful insight for designing the reliability of complex gun assemblies.
