大型船舶行驶过程沉量可靠性预测

Reliability prediction of heavy load on large ships

传统大型船舶行驶过程中沉量可靠性预测存在误差较大的问题,为此设计大型船舶行驶过程沉量可靠性预测模型。通过大型船舶实际沉量适用分析出船舶行驶过程模拟流动情况,根据分析结果计算船舶行驶运动控制参数,为沉量可靠性预测做数据准备,通过计算形式预测推导出沉量可靠性,实现大型船舶行驶过程沉量可靠性预测模型设计。通过模拟实验可以看出,大型船舶行驶过程沉量可靠性预测方法与传统方法相比,可靠性预测准确率提升16%,预测误差系数减少15%。

There is a problem of large error in the prediction process of the reliability of large ships. Out through the analysis of the large ship actual amount sink for ship driving process flow simulation, according to the results of the analysis calculation of ship motion control parameters, data preparation for heavy reliability prediction, form to predict heavy volume,reliability is deduced by calculation run large ship sink quantity reliability prediction model design. It can be seen from the simulation experiment that compared with the traditional method, the reliability prediction accuracy of large ships is 16%higher and the prediction error coefficient is 15% lower.
