Development of Loading and Axleload of Railway Common Freight Cars in Our Country;
我国铁路通用货车载重与轴重的发展
Due to import of vehicle loads and speed in damage of pavement structure,the influence on vehicles and pavement with different loads and speeds are investigated by spot experiment.
试验结果表明,车辆行驶过程中,各车轮的垂直振动加速度随着行车速度的增大而呈上升趋势;在速度一定的情况下,车辆空载与超载产生的动载效应明显要大于满载;车速为60km/h和100 km/h时,车辆后轮空载的法向荷载大于满载的法向荷载;超载行车下,车轮的法向荷载相较静载均增加;车辆空载条件下,路面动位移随着车辆速度的提高先增大后又略下降,但在满载和超载的条件下,路面动位移却随着车速的提高而增大;在车辆低速行驶时,空载时的路面动位移大于满载和超载,而在车辆高速行驶时,路面动位移是随着载重的增加而增加的。
In this paper some problems related to traffic safety such as technical grade, dynamic change, loading limit and safe mark are elaborated.
