摘　　要：为了推广路侧振动带在重庆高速公路上的应用,以货车为代表车型,基于ADAMS软件,对货车冲击路侧振动带进行了仿真试验。采用正交试验法,设计三因素四水平试验方案。根据试验结果,评价路侧振动带对货车的警示效果。试验结果表明:合理尺寸的路侧振动带对货车产生的振动加速度为1.0~1.9m/s^2,警示效果良好。各设计参数与评价指标间绝对灰度关联度为:切削式振动带的深度对货车警示效果影响最大,间距对货车警示效果影响次之,长度对货车警示效果影响最小。To promote the ruzble strips with the application in chongqing highway.Truck zodels was represented. Simulation experiment of truck hit ruzble strips was carried out based on ADAMS software.Three factors and four levels orthogonal experi-ment was designed,the ruzble strips warning effect for the truck was evaluated by theexperiment results.The orthogonal experiment results showed that ruzble strips of the reasonable size made truck vibration acceleration in 1.0 % 1.9 z /s2 , the warning effectwas good.The grey relational degree of design parameters： The depth was the maximum impact for truck warning effect,the length of ruzble strips was weaker,the spacing was the zinizuz .
