Abstract
The article concerns the developed methodology for assessing the technical condition of a tramway track. Thanks to the data collected from multiple tram journeys equipped with an on-board vibration recording system, it was possible to create profiles of crossings through track sections in different technical condition. In order to identify the track condition, an algorithm based on the gray-scale modeling was proposed, and a similarity comparison between the obtained track profiles. A new measure of similarity has been proposed that has not been used so far in gray-scale modeling. The obtained results confirm the applicability of the proposed methodology
Highlights
The execution of current research on recording the acceleration caused by tram vibrations in operating conditions, using on-board diagnostics systems and wireless data transmission, enables the track condition assessment based on the vehicle dynamic response analysis [5 ÷ 7]
This issue is very important from the infrastructure maintenance point of view, as it allows for an ongoing assessment of its technical condition in normal operating conditions
All of these factors make it difficult to estimate the track condition for light rail vehicles using the acceleration level measured in the vehicle
Summary
The execution of current research on recording the acceleration caused by tram vibrations in operating conditions, using on-board diagnostics systems and wireless data transmission, enables the track condition assessment based on the vehicle dynamic response analysis [5 ÷ 7]. The reference will be based on the passage profile for the track section in good condition.
