STATE MONITORING METHOD OF ADHESIVE INSULATING RAIL, AND STATE MONITORING DEVICE OF ADHESIVE INSULATING RAIL

摘要

PROBLEM TO BE SOLVED: To provide a state monitoring method or the like of an adhesive insulating rail capable of estimating a stress applied to a joint plate of the adhesive insulating rail based on an axle-box acceleration and irregularity in height of the rail.;SOLUTION: A stress applied to a joint plate is estimated from the axle-box acceleration at a connection part of the adhesive insulating rail measured by an acceleration measuring procedure and the irregularity in height at the connection part of the adhesive insulating rail measured by an irregularity-in-height measuring procedure, based on an estimated joint plate stress management chart showing a correlation between the axle-box acceleration and the irregularity in height at the connection part of the adhesive insulating rail, and a stress applied to the joint plate of the adhesive insulating rail. State monitoring of the adhesive insulating rail is performed based on the estimated joint plate stress.;COPYRIGHT: (C)2009,JPO&INPIT
