摘　　要：轨道车辆在投入运营前需通过静强度试验来验证其结构强度和刚度是否满足设计要求。针对EN12663标准中的抬车试验,采取两种试验方法验证了支撑点上升和下降对车体强度的影响,并借助仿真结果进行了对比验证,结果表明:仅在车体一端(或一侧)的抬车位处进行支撑点上升和下降即可以满足静强度试验的要求,不影响对车体强度的判定。Before the rail vehicle is put into operation,the static strength test should be carried out to verify whether the structural strength and stiffness meet the design requirements.Two test methods are adopted in this paper for the lifting test in EN12663 standard,verify the effect of the rising and falling of the support point on the strength of the car body,and compare the results with the simulation results.The results show that the rising and falling of the support point at the lifting space at one end(or one side)of the car body can meet the requirements of the static strength test,and does not affect the judgment of the strength of the car body.
