軌道支持状態の影響を含む分岐器の動的特性把握のための載荷実験

抄録

Usually railways regularly inspect turnouts using trained crews and special hand tools including gauges, etc. To aim the optimization of the track maintenance especially in local railways, a change in the inspection paradigm is needed that allows the inspection of turnouts in a dynamic rather than static manner in real-life conditions, i.e. a train on-board measurement. An experiment of laying track with turnout and loading to grasp its dynamic behavior including track support conditions were carried out. A comparison of measurement results confirms that the difference between unloaded/static measurements and loaded/dynamic measurements is significant.
