2103 Visualized system of the ride comfort evaluation method for practical use

Abstract

In our past studies, a ride quality index: "complex ride quality index (CRQI)" that predicts the change of ride comfort due to complex vibration was proposed, and a unified data-indication system (UDIS) as the application of the CRQI were presented. The system's users are able to watch the change of the CRQI and the existing ride quality indices together, and to grasp the shape of the acceleration-waves, the kind of the structures, and the track alignment, which exist around the spots where the CRQI becomes worse. This paper introduces the newly improved points of the UDIS for practical use and reports an analysis example using this system.
