摘要
对国内外室内车辙评价指标进行评述,通过4 h汉堡车辙试验分析了不同车辙评价指标的准确性,认为动稳定度DS能有效评价室内1 h的车辙试验,并提出应根据车辙试验初始变形对稳定度指标予以调整。
The lab rut evaluating indexes were reviewed. The accuracy of the lab rut evaluating indexes was analyzed with 4 hours Hamburger wheel Tracking test, and it was considered the dynamic stability can evaluate wheel tracking test effectively, meanwhile it suggested the dynamic stability index should be adjusted according to the initial deformation of the wheel tracking test.
