本文采用雨流计数法对货物列车车钩实测的载荷-时间历程进行统计计数,建立双参数的方阵数据表格,和变程频次直方图,为编制车钩载荷谱提供子样数据。文中简要叙述了“雨流计数法”的原理和计数规则,对进行计数前的载荷-时间历程离散压缩处理,提上了新的建议和分析方法。 In this paper, the rain-flow counting method is used to count and measure the load-time history of the cargo train coupler. The two-parameter square matrix data table and the frequency histogram of the variation are established to provide sub-sample data for the preparation of the coupler load spectrum. In this paper, the principle and counting rules of “rain flow counting method” are briefly described, and the load-time history discrete compression processing before counting is put forward with new suggestions and analysis methods.
