摘　　要：车体静强度试验是铁路车辆从设计到上线运行,再到车辆的转场生产过程中最基本也是最重要的一项型式试验,对车体结构的设计具有引导作用,对仿真计算模型、方法及结果的合理性和准确性具有验证、修正及促进作用,对转场车辆的生产、出厂具有重要的保障作用,可见如何合理准确的依据标准完成车体静强度试验,得到相关精确试验数据对铁路车辆的安全运行是非常重要的。结合国内铁路货车车体静强度试验现状,主要依据TB/T 3550.2—2019《机车车辆强度设计及试验鉴定规范车体第2部分:货车车体》对铁路货车车体静强度试验的内容、载荷值及方法进行了分析研究,同时对试验中可能遇到的问题进行了总结,并给出了建议。The static strength test of carbody is the most basic and important type test in the process of railway vehicles from design to the service on-line,and then to the transfer production of vehicles.It plays a guiding role in the design of carbody structure,verifies,corrects and promotes the rationality and accuracy of simulation calculation models,methods and results,and plays an important role in ensuring the production and delivery of transfer vehicles.It can be seen that how to complete the static strength test of carbody reasonably and accurately according to the standard and get the relevant accurate test datas is very important for the safe service of railway vehicles.Combined with the current situation of domestic railway freight carbody static strength test,according to TB/T 3550.2-2019“Strength Design and Test Accreditation Specification for Rolling Stock-Carbody Part 2:Carbody of Freight Wagons”,the content,load value and method of static strength test of railway freight carbody are analyzed and studied.Meanwhile,the possible problems in the test are summarized and suggestions are given.
