摘要:
为了考察流固耦合关系下列车高速交会的安全特性,防止气流与列车相互作用对列车结构和运行安全性造成过大影响,综合计算流体动力学的有限体积法和系统动力学的分析方法,提出一种新的更符合实际的列车交会流固耦合振动仿真方法,同时求解流场方程和系统动力学方程,并采用流固耦合方法和传统的分离方法对350 km/h 等速交会安全性进行分析,综合2 种方法所得结果与线路试验数据,证明了流固耦合仿真方法的有效性,并分析了2 种方法的差异。采用流固耦合方法更能保证列车高速交会安全性。
Abstract:
In order to study safety of train passing by each other with consideration of fluid-solid coupling friendship and avoid the large damage to structure and running safety from the interaction of train and air, a new numerical analysis method of fluid-solid coupling vibration was advanced by integrating the finite volume method of computational fluid dynamics and numerical simulation method of multi-body systems dynamics, with which the flow field equations and dynamics equations of multi-body systems were solved. Safeties of trains passing by each other at speed of 350 km/h were analyzed by fluid-solid coupling method and traditional separation method respectively and compared to line test, which showed that fluid-solid coupling method was valid. And with difference analysis of the two methods, the coupling method was proved safer.
