| 摘 要： | 为研究重型运输车辆对高等级路面作用的动荷载,建立1/2车辆动力学模型,研究了路面不平度、车辆速度、轴重和胎压等因素对车辆动载荷的影响。研究结果表明:车辆动载系数随着路面不平度、车辆速度和胎压的增加而增加,随着轴重的增加而减小;车辆动载荷随着各个参数的增加而增加;标准载荷下,A级路面动载系数为1.12~1.19,B级路面动载系数为1.23~1.38,C级路面动载系数为1.48~1.76,D级路面动载系数为2.00~2.52。

| Abstract: | To study the dynamic load on high-class pavement coming from heavy vehicle,a dynamic vehicle mode was developed.The influences of pavement roughness,the vehicle speed,the axle load and the tire pressure on the vehicle dynamic load were studied.It's found that the load coefficient increases with the increase of pavement roughness,the vehicle speed and the tire pressure,yet it decreases with the increase of the axle load.The dynamic load increases with the increase of the factors above list.The dynamic load c... |
