青藏铁路建设给现有的主要依靠空气制动的列车带来难题。由于是高原气候条件下空气稀薄大气压力低,必然会影响到气体制动波信号的传递而危及行车安全。文章对既有空气制动系统受到的局限性和可能面的临诸多问题进行了分析和预测,提议改进现行的制动系统试验方法和标准,并配备相应的计算机模拟仿真操作系统,以期达到保证在复杂环境下能正常运作之目的。
The construction of the Qinghai-Tibet Railway poses problems for the existing trains that mainly rely on air brakes. Due to the low atmospheric pressure of thin air in the plateau climate, it is bound to affect the transmission of gas brake wave signals and endanger traffic safety. The paper analyzes and predicts many limitations of the existing air brake system and its possible problems, proposes to improve the current braking system test methods and standards, and equips the corresponding computer simulation operating system in order to achieve the guarantee In a complex environment, the purpose of normal operation.
