Title:

Preliminary Development of a Mechanical Empirical-Based Wearing Model for the Conductor Rail in a Medium Capacity Transit System

Accession Number:

Abstract:

Currently, there are various types of railway systems, among which is the Medium Capacity Transit System (MCTS) which in some countries, uses rubber-tired trains. Rubber-tired trains are powered by electricity through sliding contact between the conductor rail system and collector shoe. The sliding contact produces wear on the conductor rail and wear plate which resulting in malfunction of the electricity supply. Track management system (TMS) is usually adopted to facilitate the track operation, and one of the key components of the TMS is the performance model. Generally, there are three types of performance models: empirical, mechanical, and mechanical empirical (ME). However, there is no study on the ME based wearing performance for conductor rail systems at present. Therefore, there is an urgent need to develop ME-based wear deterioration model that makes it possible to determine the in-service condition. There were three types of data collected to establish the ME-based wear model for conductor rail system in the MCTS. The first was the wear plate, conductor rail, and collector shoe specifications. The second was the data related to service condition. The third was the wear plate and conductor rail inspection data. There were two proposed ME-based wear models, one for the wear plate and the other for the conductor rail. The result of the ME-based wear model for the wear plate showed that the higher the wear level, the lower the percent error. For the conductor rail, the percent errors were irrelevant to wear level and were stable below 16%.
