Method for measuring contact position between wheel and rail of railway vehicle and method for measuring lateral pressure of railway vehicle using the same

摘要

Problem to be solved: to provide a method capable of measuring the contact position between a wheel and a rail of a railway vehicle on the track side and a method capable of accurately measuring the lateral pressure of a railway vehicle on the track side.A method of measuring a contact position of a rail of a railway vehicle and a rail r of a track running by a railway vehicleMeasurement of wheel weight and lateral pressure on the track sideMeasure the amount of repulsals measured by the orbit on the track sideWheel weight and lateral pressure measured in the wheel and transverse pressure measurement steps.Based on the amount of repulsals of the rails measured in the regression measureContact position calculation step for calculating contact position.Further, the horizontal load calculation step for calculating the horizontal load acting between the wheel and the rail based on the wheel weight and lateral pressure measured in the wheel and lateral pressure measuring step and the contact position calculated in the contact position calculation step is included.Diagram
