摘　　要：简述了轨道交通整体承载式铝合金车辆车体挠度试验原理,以及车体挠度预制试验方法。对车体挠度预制试验和垂向加载试验结果进行了分析。结果表明,车辆整备和超员加载试验后车体垂向位移为9.95~11.14 mm,车体剩余挠度为2.80~5.05 mm。由此证明,车体挠度预制可以有效抵抗垂向载荷产生的位移,使车辆运行过程中不会发生下凹变形。The deflection test principle of rail transit integral load-bearing aluminum alloy vehicle body and the prefabrication test method of car body deflection are briefly described,and the results of car body deflection prefabrication test and vertical loading test are analyzed.The research shows that after the vehicle servicing and overload loading test,the vertical displacement of the car body is 9.95~11.14 mm,and the residual deflection is 2.80~5.05 mm.This proves that the deflection prefabrication of car body can effectively resist the displacement caused by vertical load,in this way,the concave deformation is not easy to happen during train operation.
