摘　　要：采用材料力学的理论和方法,对轨道衡称量台进行单个集中载荷、2个集中载荷、均布载荷等受力模型进行分析,得出每种载荷作用下梁的挠度计算公式。然后对GCU-150D轨道衡进行加载试验,模拟轨道衡工作时的受力情况,测量试验点的变形数据,通过理论计算数据与试验数据的对比分析,得出均布载荷的受力模型是符合实际的结论。By using the theory and method of mechanical of material, the rail weight-bridge is investigated with single concentrated load, two concentrated loads and uniform load, each deflection formula is obtained. Then, load test of GCU-150D which simulates the work case is carried out.The deformation data of the testing point is measured. Through comparing of theoretical calculations and experimental data, can conclude the uniform load of force model is well compared with the practice.
