摘　　要：利用拖拉机原始载荷谱及试验数据对比,通过不同车辆间的试验标准对比,分析轮式拖拉机前轴疲劳试验标准中关于最大载荷的选取,表明标准JB/T 9828-1999规定的疲劳强化试验最大载荷的选取偏大,并对如何选取最大试验载荷进行了探讨。Through comparison between the tractor＇s load spectrum and the testing data,and compared with other vehicle testing standard,we study the choice of upper force to the wheeled tractor＇s front axle in testing standard.It is concluded that the choice of upper force is bigger which is specified by the standard JB/T 9828-1999 in fatigue intensifying test,and how to choose the upper force in this paper is discussed.
