车桥及车轨时变系统横向振动计算中的根本问题与列车脱轨能量随机分析理论
|
摘要
本文论述了车桥及车轨时变系统横向振动计算中存在的根本问题。介绍了作者们解决这些问题的思想与方法 ,提出了列车脱轨能量随机分析理论。用此理论预报了一货物列车脱轨实例 ,与实际发生的脱轨事故吻合。判别了另一脱轨试验列车不脱轨 ,计算了该试验列车最大振动响应 ,与测试结果良好接近
In this paper, the fundamental problems in the calculation of transverse vibration of train bridge and train track time varying system are expounded. Our thought and our approach to these problems are introduced. The theory of energy random analysis for train derailment is presented. Using this theory, authors have forecast the actual freight train derailment, which is in conformity with the actually accident occurred. They also have identified another experimental freight train being not derailed, and calculated its maximum vibration responses. Our calculation results are very close to those obtained from the field test.
