摘要
为了确定汽车耐久性试验中试验场路面与普通路面的强化关系,文章以某型越野车为研究对象,确定了用户实际使用时各种普通路面总的目标里程及载荷谱的雨流矩阵,并获取试验场各路段的载荷谱及其雨流矩阵;基于雨流矩阵一致的原则,计算了试验场各路段比例和总里程,得到了试验场路面相对于普通路面的强化系数。
Abstract：In order to determine the enhancement relationship of proving ground road and normal pave- ment in vehicle durability test, a sport utility vehicle（SUV） is chosen as the research object. The total load spectrum rain-flow matrix of the normal pavement in practical use is determined, and the load spectrum and rain-flow matrix of the various sections of proving ground road are obtained. Based on the consistence principle of rain-flow matrix, the proportion of the various sections of proving ground road and the total mileage are calculated, and the obtained as well. enhancement coefficient of proving ground road is
