摘要
以推导出的估计随机变量函数平均值和标准差的近似公式为基础,提出拖拉机载荷分析的概率方法;分析了拖拉机机组在纵垂面内的载荷,并将分析结果与测试结果作了比较.
The probabilistic analysis of wheel tractor service load, based on the derived approximate formulae for statistical estimation of random variable function, is presented and illustrated, and the service load in longitudinal vertical plane of a tractor unilt is analyzed. A comparison between the probabilistic analysis results and the experimental ones is also made.
