前言我们把本文推荐给读者,为的是使读者对目前正在运用中的法国国营铁路机车车辆部件采用的无损检测有一个总的了解。一、导言铁路公司历来对铁路运输的安全性甚为关注,他们很早就对某些零件和构件进行个别的和系统的检测。随着材料工艺的发展,运行速度和运输载荷的提高,有必要检查整个构件中每个构件的正常使用年限,并注意提高它们的使用寿命。为此,应发展对装置使用寿命没有影响的无损检测方法,同时也应利用该领域中所有可以利用的工业技术潜力。二、各种无损检测技术
Preface We recommend this article to the reader in order to give the reader a general overview of the non-destructive testing used in the French State-owned rolling stock components currently in operation. I. INTRODUCTION Railways have always been very concerned about the safety of railway transport. They have conducted individual and systematic tests on certain parts and components very early on. With the development of material technology, the speed of operation and the increase of shipping load, it is necessary to check the normal service life of each component in the whole component and pay attention to increase their service life. To this end, non-destructive testing methods that have no effect on the useful life of the installation should be developed, taking into account the potential of all available industrial technologies in this area. Second, all kinds of non-destructive testing technology
