13号车钩段修样板检定规程 - Coupler gauge no . 13 used for department repair
13号车钩段修样板 - Wheel set is one of the most important rolling components in the vehicle . it affects the safety of railway transportation directly . our country ' s train vehicle departments have specific standards about wear and tear limit of all kinds of wheels
我国铁路车辆部门对各型轮对的磨耗限度均有明确的规定，在段修时对轮对综合参数进行检测是保障行车安全的一项重要措施。 - By the result of these experiments , acoustic emission ( ae ) was chosen to use in the research . at the same time , we analyse the phenomenon of acoustic emission at the base of theory , the characteristic signal of acoustic emission which comes from the faulty bearing at the angle of application , and the expression of the characteristic signal . contrast was also made on the data achieved separately from vibrational signal and ae signal , and it is proved that ae is feasible and available to the diagnosis to the fault of the rolling bearing
主要工作有如下几方面：对本段前期实验室阶段采用的振动法幅值域无量纲处理进行了分析，并研制了现场所使用的滚动轴承故障检测装置，将无量纲参数诊断法应用于段修现场，且做了大量试验；对于现场试验中所出现的问题进行了分析，提出将声发射的方法用于轴承的在线故障诊断；从理论上分析了声发射现象，从应用的角度分析故障轴承的声发射信号的特征以及声发射信号特征的表示方法，并在实验室中，采用振动法和声发射法实时检测的实验数据进行了对比和分析，证明了使用声发射法对轴承故障检测的可行性和有效性。 - Measuring parameters of wheel set is a necessary step for protecting transportation safety . but in our country , the measurement was done by using hands mostly . with the speedup of train , the current detecting methods could not meet the requirements of wheel maintenance
目前，我国铁路车辆轮缘几何参数、轮对尺寸参数和踏面缺陷参数测量大多还停留在手工阶段，特别是列车提速以后，现有检测方法已不能满足车辆段修的要求，需要研制一种较高精度和可靠性的轮对综合参数自动化检测系统。
