本文提出了按单一路面载荷谱进行强化程序疲劳试验的新方法,并根据试验结果建立了EQ140汽车后桥极值——寿命曲线和不同路面之间实际行驶里程的当量关系,可预估汽车在各种路面上混合行驶条件下的使用寿命。
In this paper, a new method of fatigue test based on load spectrum of a single road surface is proposed. According to the test results, the equivalent relationship between the extremum-life curve of the EQ140 rear axle and the actual distance traveled between different road surfaces is established. A variety of road conditions under mixed driving conditions.
