摘要
在建立储油罐液固耦合振动方程基础上,采用大型通用有限元分析软件ANSYS对制动状态下铁路车载容器的动态响应问题进行了实例分析和计算.建立了车载油罐的液固耦合系统有限元模型,并且对列车制动条件下的满载和空载储油罐进行了瞬态仿真分析,绘出了制动时油罐不同时刻的变形图和均方应力最大点的幅值图,将满载和空载的车载储油罐分析结果进行了比较.分析结果可以为储油罐的结构动力学设计提供参考,为提高车载储油罐的可靠性提供数值依据.
Based on the fluid - solid coupled dynamic equation, the fluid - solid coupled dynamic response of the train oil tankers are analyzed with finite element software ANSYS when the tanker is braked. The finite element model of the containers is built. Moreover, the simulation dynamic response of the container with full load and empty is analyzed when train is braked. Also, the deformation pattern of container and the graph of the maximum stress response are drawn. The response results of containers full load are compared with those empty. So the results provide the reference for the structural design of the train oil tankers and the numeric evidence for improving the reliability of the train container.
