以新型煤炭漏斗车车体研究对象,把物理模型转化成有限元模型,对该车体空车和重车工况分别进行了有限元静强度分析、刚度分析.同时按照《铁道车辆强度设计及试验鉴定规范》进行了样车强度刚度实验,并将计算出的结果与样车的测试结果进行了对比分析,对比结果不仅验证了数值计算的可靠性,而且为进一步在设计期间的车辆疲劳寿命预测提供了基础数据. Based on the research object of the new coal hopper car body, the physical model was transformed into the finite element model, and the static strength analysis and stiffness analysis of the empty car and the heavy car were carried out respectively. At the same time, Test identification specification "carried out a sample of the strength and stiffness test, and the calculated results with the prototype car test results were compared and analyzed, the results not only verify the reliability of numerical calculations, but also for the further in the design of the vehicle fatigue life Forecast provides the basic data.
