在货车编组和长度不断增加的情况下,现在使用的机车空气压缩机(以下简称空压机)的风量是否应随之增加?不同风量的空压机,对于货车空气制动机的充气和缓解时间,会带来什么影响? 为回答这些问题,美国机诫系统通用电器运输公司的主任工程师Geoffrey Perkins等人设计了一个试验装置。按照不同风量的空压机、不同辆数的列车编组,不同速率的列车管漏泄量的排列组合,在纽约空气制动机公司的200辆货车试验台上,进行了试验。根据试验结果,抽象出流动气体质量、压力、温度相互关系的数学模型,并对上述问题做出了结论性的答复。
In the case of an increasing number of trucks and their length, should the air volume of the currently used locomotive air compressors (hereinafter referred to as air compressors) be increased? Air compressors of different air volumes will inflate and relieve the air brake of the truck Time, what impact? To answer these questions, Geoffrey Perkins, lead engineer at General Electric Transport Systems, a U.S. warning system, designed a test rig. In accordance with the air volume of different air compressor, train number of different groups of train leakage at different rates permutation and combination of the train, in the New York Air Brake 200 truck testbed were tested. According to the experimental results, we abstract the mathematical model of the relationship between the mass, pressure and temperature of the flowing gas, and conclude the above questions.
