摘　　要：通过大量试验和统计,得出了在良好、较差柏油路面条件下,载货汽车前轴垂直动态载荷幅值、均值、最大值随行驶车速和前轴静态轴荷的变化规律。前轴垂直动态载荷最大值主要受前轴静态轴荷的影响,与前轴静态轴荷成线性关系,并且90%概率下与前轴静态轴荷的比例不超过1.4。Through a great deal of tests and statistics,get the change rule of truck front axle vertical dynamic load amplitude,mean value,maximum value with the changes of running speed and front axle static axle load under the condition of good and bad asphalt road.The maximum value of front axle vertical dynamic load is mainly affected by front axle static axle load,and is the linear relation with front axle static axle load,the ratio to the front axle static axle load is not more than 1.4 under the condition of 90 % probability.
