摘要：

随着高速铁路的快速发展,为了适应高寒多风沙环境,设计封闭式设备舱.在过隧道和交会等恶劣工况下,封闭式设备舱容易产生较大压差.采用动模型试验方法,对动车组以不同车速（200、250、300 和350 km/h）通过隧道和隧道内交会进行试验模拟,建立相应的数值计算模型来相互验证.结果表明,数值计算与动模型试验波形吻合,幅值相差低于6-8%.对于单车过隧道,车体表面和设备舱内压力峰峰值与车速的平方呈线性关系.对于隧道内交会工况,车表面压力对于速度更加敏感,车体表面压力峰峰值与车速的三次方呈线性关系.设备舱内压力峰峰值明显小于车外表面压力峰峰值.设备舱内不同位置处的压差峰峰值有明显波动,相对隧道中心交会而言,单车过隧道工况对速度更敏感.
Abstract:

 A closed equipment cabin was designed to help train adapt the high, cold, wind and sand environment with the rapid development of high speed railway. While trains going through and crossing in tunnel, there will be a big differential pressure appear in the closed equipment cabin. Highspeed trains going through and crossing in tunnel with different speeds (200, 250, 300 and 350 km/h) were simulated by using dynamic model test method. Results of numerical simulation and test data were verified by each other. Results show that pressure waveforms of numerical simulation and test data were consistent, and amplitude difference between them was less than 6.8%. For the conditions of train going through the tunnel, there is a linear relationship between the amplitude of train surface pressure change and the square of train speed. For the conditions of trains crossing in the tunnel, the surface pressure is more sensitive to velocity, and there is a linear relationship between the amplitude of train surface pressure change and three power of train speed. The pressure change amplitude inside equipment cabin is significantly smaller than the one of train outside surface. The differential pressure change amplitude inside equipment cabin at different positions fluctuates significantly, and differential pressure caused by train going through tunnel is more sensitive to velocity than the one caused by train crossing in tunnel.
