舰船总体性能可靠性建模方法研究

分析了舰船总体性能可靠性问题的产生原因,将其分为2类.对于舰载设备本身存在可靠性问题而造成的,以航速可靠性为例,在舰船总体可靠性的背景下,借助相关数学工具进行了建模方法分析;对于外界随机因素影响而造成的,如横稳性的可靠性问题,则从分析外界随机因素与船体设计参数之间关系入手.初步建立了一套研究舰船总体性能可靠性问题的建模方法.实例计算表明,将所建模型用于分析舰船总体性能比常规方法具有明显的优越性.

On reliability modeling methodology for design performance of naval vessel

The causes of the reliability problem of general performance of the naval vessel are classified into two sorts: one which is caused by reliability problems of the equipment,such as the reliability problem of sailing speed,a modeling method by dint of mathematical theories can be used based on the general performance of the naval vessel,the other one caused by random factors from the environment,for example,the reliability assessment of the transverse stability,the method by analyzing the relation between random factors and design variables is presented.So a series of modeling methods of reliability for the general performance of the naval vessel are established.The result from an actual example shows that the models are superior to the current methods.
