摘要: 针对高速列车穿越隧道或两车交汇时产生的车外压力波会对车内旅客会产生"耳感不适"这一问题提出了新型压力控制方案,本文对新型压力控制方案进行了模拟试验论证.模拟试验系统主要由模拟车厢、进气系统、车外环境模拟系统、间接式气动压力调节器及数据采集系统五个子系统组成.整个试验内容包括压力调节器阻力特性试验、车外压力为负压时的静态试验、车内压力为正压时的静态试验及车外压力变化的动态试验.试验结果表明,采用新型压力控制技术,高速列车车厢内的压力指标能达到所要求的设计要求,进一步验证计算机模拟分析的正确性,同时论证了本方案的可行性.

Abstract: When two rapid trains travel in tunnel or encounter, there will take place enormous pressure wave which makes passengers uncomfortable. In order to release the pressure wave, the new-type pressure control technology which borrow ideas from airplane's cabin pressure control program is analog tested. The test simulation system include simulation cabin, air inlet system, exterior ambient simulation system, indirect pneumatic pressure regulator and data acquisition system. The test content contain the resistance character of pressure regulator, the static test which exterior ambient is in negative pressure and in positive pressure, the dynamic test which the exterior ambient is variable. the result confirms that the computation analysis is correct and demonstrates that the cabin's pressure is the satisfied with the pressure target , also shows that the present technology is practical.
