摘　　要：以小型客车通过减速带时引起的地面振动加速度的波谷极值作为研究指标,根据正交试验设计,并应用直观分析法和方差分析法,探讨行驶车速、减速带类型、减速带材料和路面表层材料4个影响因素对研究指标的影响程度和最优方案组合。结果表明,行驶车速的极差R和方差分析F值最大,路面表层材料的相应数值最小;行驶车速大于某一临界车速时,车速对研究指标的极值影响突变显著;试验得到的最优组合方案为"低速+沥青路面+橡胶减速带+加强型减速带"。The experimental index of study is the extreme values of the vibration signal. By using the orthogonal design and variance analysis and range analysis, it studies the influences of four factors including speed, types of speed bumps, material of speed bump, material of the road on the surface and the optimum mix proportion. The results indicated that the speed got the maximum value in both range analysis and variance analysis. The material of the road on the surface got the minimum value. The speed was an important influence for the significant mutations of the experimental index when it reached the critical value. The optimal mix proportion is ＂the low speed through the speed bumps, the asphalt as the material of the road on the surface, the rubber as the material of the speed bumps, the type of the speed bumps is enhanced＂.
