摘　　要：根据影响车辆随机动态荷载的主要因素,在设定的多层次指标体系的基础上,将层次分析法(AHP)用于随机动态荷载的评定中。该方法将复杂的车辆随机动态荷载问题分解成若干层次,在各层次上对随机动态荷载进行定量分析。根据分析结果,建立了随机动态荷载的分级标准,为合理荷载模型的确定提供了依据。The Analytical Hierarchy Process （AHP） was used to assess the random dynamic loads of vehicle based on the specified hierarchical index system, according to the main factors which affects the random loads. With application of AHP method complex random loads of vehicle arc disintegrated into several parts, and then quantitative evaluation is made for random loads. Based on the analytic results, classification criterion of random loads is established which can provide foundation for logical loads model.
