本研究推導軌道車輛行駛下輪軸動態力平衡方程式,並透過文獻探討,確認縮尺比例模型與全尺寸結構之差異後,設計1:5縮尺比例全轉向架模型,用以量測輪軸力平衡方程式上所需之車輪慣性力與懸吊彈簧力量,代入輪軸力平衡方程式後,即可求解輪軌接觸之垂向力(P力)與橫向力(Q力)。

透過本研究所開發的車載量測方式,確實可以量測到不同時速下,輪軌接觸之垂向力(P力)與橫向力(Q力)之變化,並計算出脫軌係數。本研究之成果,可以平價、安裝簡便、即時量測、隨車量測的方式進行脫軌係數量測,期待未來能於實車上安裝,進行大數據收集與分析,以精確評估列車脫軌特性。未來並希望能修正輪軸動態力平衡方程式、並且增加橫向外力,以評估地震力與風力帶來的影響,讓整體系統具有更高的實用價值。

The wheel-rail contact force is the key factor of the railway vehicle running safety. This study aims to find the vehicle-based method for measuring wheel-rail contact force on-board. The method is based on the dynamic force equilibrium of wheelset. The vertical and lateral contact force is able to be determined while some sensors are used to measure the dynamic responses of bogie for the other necessary information.

In order to verify the correctness of the method, a 1:5 scaled bogie with rolling ring is developed to perform the experiment. Laser displacement meters are used to measure the compression of the suspension spring for determining suspension force. And acceleration meters are used to determine the dynamic inertia force while the wheelset is moving. Then the vertical (P force) and lateral (Q force) wheel-rail contact force can be solved through the equations of equilibrium.

Finally, the derailment coefficient can be calculated by P and Q force to evaluate the running safety of the railway vehicle under different running speed. A convenient method with cheap devices are proved to be able to measuring the real time wheel-rail contact force on board. Hope that this method can be used to prevent the disaster (such like earthquakes) to the railway vehicle in the near future.
