“…Most researchers deal with thermal fatigue as a special case of isothermal fatigue. Many researchers have worked on numerical simulation models [41][42][43] to create better understanding of thermo-mechanical stresses which are produced during the process and are responsible for failure of components.…”

“…This is because multiple dimensions are relative. 2 If there is error in some dimension, the dimensions in other parts are also influenced. In order to explain clearly, here the definition of wheelset's parameters and experimental principle are illustrated firstly.…”

“…The traditional methods still more depend on the special mechanic tools like artificial calipers. 2 Although it is easy to be implemented, there are the problem of high labor intensity, low efficiency and low accuracy. With the development of image processing and camera technology, non-contact measurement gets more and more attention and is widely applied in practical dynamic measurement of various parts.…”

In order to develop the geometric parameters measurement technology of wheel tread, it is important to ensure the positioning precision firstly before measurement. In this paper, a new method with no-contact measurement based on line structured light is given to solve this problem. Here the traditional mechanical locating method is used as a rough reference. Then, according to the feature points (particularly, the key points that have not been worn), the precision positioning is adjusted dynamically based on the calculated results of non-contact measurement. With the developed digital image processing techniques, the line structured light on the wheel tread is extracted effectively. Thus the pixels of the extracted line structured light can be transformed to the real geometric dimensions. In this paper, the experiments show that it improves the accuracy of positioning and reduces the factors of measurement errors with the proposed method, and it is possible to implement non-contact measurement of the wheel tread, wheel flange thickness and flange width.

“…Principally, the present maintenance strategy in China is still plan-based, which induces a huge amount of unnecessary maintenance and related cost. Take the case of wheels, as one of the most important components of the bogie, they bear the load, guide the direction of the locomotive, and suffer a diversity of damage modalities such as cracks, fatigue, corrosion, scratch, and wearing [15]. According to the literature [16], [17], train wheel failures are the cause of half of all train derailments and costs the global rail industry billions of dollars each year.…”

Condition-based maintenance is a more advanced maintenance strategy, owing to reducing inspection and maintenance costs and improving the reliability of targeted assets. The maintenance strategies in the Chinese Railway industry are transforming from plan-based to condition-based, which has heightened the need for the completion of relevant research. This study proposes an experience-based health status evaluation method for train wheels, which considers factors in the wheel manufacturing process, operational process and maintenance process. The manufacturing factors are indicated by material properties and press-fitting influence factor, while operational and maintenance factors are indicated by wheel diameter and damages. Based on the health evaluation values, a decision-making function is constructed to divide wheels into four categories: fine, attention, pre-alarm and scrapped. Finally, the PHM + Wheel system is developed based on the proposed health evaluation method to provide support for maintenance strategy. The PHM + Wheel system has been practically applied to the Chinese Railway industry with adequate feedback received. INDEX TERMS Prognostic and health management, train wheels, health status evaluation, prognostics.
