摘要 动车组在隧道和在明线上交会时, 均会引起车外较大的压力波动。一般而言, 动车组通过隧道所产生的压力波动比明线上两列动车组交会所产生的压力波要大。车外压力波动传入车内会引起空气压力波动,从而冲击司乘人员的耳膜, 造成耳鸣、耳痛等, 带来动车组内压力舒适度问题。减缓车内压力波动的主要措施之一是采用气密性能良好的车辆。这就带来了如何评价车辆气密性的问题。
风挡、渡板位于客车车体端部, 是构成通过台的主要部件。通过台是车辆之间相互连接的通道和旅客进出的必经之路, 必须保证其安全。其中, 风挡为关键部件, 技术含量比较高, 为主要研究对象。
为了能够有效准确的测量出动车风挡气密性，本文介绍了在实验室中通过硬件的搭设，经过气动装置，对风挡部件进行充压与抽压，从而模拟出风挡在动车高速运行的状况下，风挡内部的压力情况。通过亚当模块对风挡内部压强进行抽样采样，并通过数模转换模块进行A/D转换。通过RS-485总线与计算机相互通信，继而通过由vb设计的操作系统程序，对风挡内部压力值变化进行测量，并绘出曲线图，通过excel输出打印。然后对比国家标准，得出该风挡气密性是否符合国家标准的结论。整个系统实现对密封风挡进行正负压充压，压力值抽样，数模转换，软件自动绘图，打印输出等功能。

Research and Design of EMU windshield tightness test system
Abstract EMU pass the tunnel and in the intersection next line will cause the vehicle greater pressure fluctuations. Generally, EMU volatility generated by the pressure tunnel large than the pressure wave next two columns online EMU intersection generated. Vehicle pressure fluctuations incoming interior can cause air pressure fluctuations, Thus the impact of the eardrum of staff and passengers, Cause tinnitus, earache, etc., to bring the problems of pressure inside EMU comfort. One of the main measures to mitigate the pressure fluctuations inside the car is good air tightness performance of vehicles using. This leads to problem of how the eva luation of tightness of the vehicle.
Windshield, crossing the plate located at the ends of the coach body is constituted Taiwan's major components. After a pneumatic device 。Through Taiwan is interconnected between the channel and the passenger vehicle only way out. Must ensure their safety. Among them, the windshield is a critical component, technical content is relatively high, as the main object of study.
To be able to effectively and accurately measure out the windshield tightness of EMU, This paper describes the hardware in the lab erection, After a pneumatic device. Stamping and pump pressure parts for windshield. In order to simulate the condition of the motor car windshield high-speed operation, the pressure inside the windshield situation. By the internal pressure of the damper module Adam sample sampled and a / d conversion by converter module. Through the RS-485 bus and the computer communicate with each other, Followed by Operating system program by visual basic, Changes in the value of the internal pressure on the windshield measure. And draw graphs, and printout in excel. And then compared with national standards, Come to the conclusions that the windshield tightness meets national standards. The whole system to achieve positive and negative pressure on the sealing windshield carried stamping pressure sampling, digital to analog conversion, software, automatic drawing, print output function.
