台車振動加速度による状態監視手法

摘要

Sound monitoring of railway vehicles is essential for securing ride comfort and safety for passengers. However, the sound monitoring system equipped with many sensors may not only be expensive, but also require much expense for maintenances of the sensors. Therefore, we have developed a system to evaluate the sound conditions of railway vehicles with fewer sensors. In this paper, we demonstrated the system under development detected damping malfunctions of an axle damper or an air spring, a puncture of air springs and a derailment that caused singular vertical acceleration with only one accelerometer on a bogie.%安全性や乗心地に直結した台車部品の不具合や走行状態を監視するシステムについて，1台車に1個ないしは2個程度の少ないセンサで状態を監視する手法について検討した。
