碩士 === 國立成功大學 === 土木工程學系專班 === 92 === In order to allow track maintenance personnel to determine impacts of track irregularities on traffic safety and to execute maintenance on dangerous sections, This study provides an analysis method with the application of ADAMS/Rail, modified train model suitable for track with a track gauge of 1067mm, and model track made to parameters actually taken from a section of measured irregularities of Taiwan Railway Administration. Using wheel-track counter-canceling behavior function built in the software to conduct dynamic analysis of train, we are able to understand mechanic behaviors in all parts of track system, and analyze the most critical safety issue in transportation. In addition to understand the influence that irregularities parameters of integrated track impose on traffic safety, the influences that other irregularities parameters of individual tracks (irregularities parameters of track can be categorized into vertical irregularities parameters and horizontal irregularities parameters) impose on traffic safety is also one key issue in our analysis. This study categorizes parameters into three groups, which are vertical irregularities of track, horizontal irregularities of track, and integrated track misalignment, for dynamic analysis of train, and each of which is assessed for traffic safety influence. This study analyzes all types of track irregularities that influences traffic safety. Derailment quotient(Q/P) for every wheel on every bogie does not exceed 1 as regulated, and are far below regulated level. That means under 1067mm maintenance regulation, parameter of track irregularities of such section should not endanger traffic safety. It can also be concluded that results from the analysis method provided by this study can be considered as a reference for determining traffic safety of train.
