軌道情報を含む乗り心地情報一元表示システムの開発と活用

摘要

We develop a unified data-relevant-ride-comfort indication system (UDIS) as an application of the CRQI. The CRQI is a ride quality index: "complex ride quality index (CRQI)" for predicting the change in ride comfort due to complex vibration, which was proposed in our previous studies. The UDIS's users are able to watch the change in the CRQI and that in the existing ride quality indices together, and to grasp easily the acceleration-data, the existence of some structures like tunnels, and various track-information around his or her target spots. This paper introduce the UDIS by showing some its application examples in some fields.%鉄道分野の振動管理は，左右•上下•前後といった方向別に行われることがほとんどであり，快適性に関わる振動乗り心地も同様である。その主な理由は，測定の簡便性と管理上の利便性にあるといえよう。しかし，乗り心地は「旅客がどう感じるか」で決まり，旅客が体感するのは，様々な方向の成分が混在した振動(複合振動)である。
