車両の走行安全性向上のための軌道の複合管理指標の開発に向けた基礎的検討

抄録

Among the track geometries, the combination of alignment and cross-level was determined based on the running characteristics of the two-axle freight cars that were operated during the JNR era, so it is not necessarily an optimal index for the rolling stock with two-axle truck currently in operation. Therefore, it is necessary to clarify the range of application to the running safety of current vehicles and to review the composite index. In this paper, as a fundamental study to meet such demand, we analyzed the actual distribution and progress of various track geometries in the current section that manage the combination of alignment and cross-level, and the impact of these track geometries on the vibration of passenger vehicles.
