摘要

摘要铁路安全一直是一个重要的课题。无论是基础设施还是机车车辆,安全问题都是最重要的永久问题,反映在任何运输系统的效率中。本文主要研究铁路油罐压力容器的安全使用问题。关于这个主题有很多文章和作品,众所周知,在设计、执行、操作和维护方面都有国家和国际法规。此外,关于BLEVE(沸腾液体膨胀蒸汽爆炸)现象导致材料损坏和重大伤亡的报道也不少。BLEVE型爆炸不被视为源自气体-空气爆炸环境(也存在于不可燃气体中)的化学爆炸,而是通过过度加压的机械爆炸。因此,我们建议对使用理论方法获得的结果与在这种油轮上进行张力测量获得的结果进行比较研究。

Comparative Study on the Applicability of Analytical and Experimental Methods in the Analysis of the Safe Use of Rail Tankers Carrying Petroleum Products Under Pressure
Abstract The safety of railways has been and remains a critical topic. Whether it is infrastructure or rolling stock, the issue of safety is a permanent concern of the utmost importance, being reflected in the efficiency of any transport system. This paper focuses on the safety in operation of pressure vessels that equip railway tanks. There are many articles and works on this subject, and it is well-known that there are both national and international regulations regarding their design, execution, operation and maintenance. Also, there are quite a few reports on the BLEVE (Boiling Liquid Expanding Vapour Explosion) phenomenon resulting in material damage and significant casualties. The BLEVE-type explosion is not considered a chemical explosion derived from a gas-air explosive environment (also present in non-flammable gases), but rather a mechanical explosion through over-pressurization. Thus, we propose a comparative study between the results obtained using theoretical methods and those obtained as a result of tensoresistive measurements on such a tanker.
