摘要

論文主要是利用多體動力學SIMPACK分析軟體結合SIMULINK動態模擬軟體，來建立輕軌車輛剛柔耦合模型和牽引系統模型，並進行動態與牽引性能模擬分析。首先，建立捷運軌道車輛的多體動力學模型與牽引系統模型，模擬所得結果並與實際列車結果進行比對，確認模擬模型之準確性。接著，建立輕軌軌道車輛的多體動力學模型與牽引系統模型，來進行車輛動態性能與馬達性能之模擬分析。
　　分析結果顯示，捷運軌道車輛分析所得馬達消耗總能量為247 kWh，與實際功率相比誤差為5%，確認模擬模型之準確性。此外，整車動態模擬所得輕軌車輛所需馬達扭矩及功率分別為674 N-m及63 kW。在本文所提路線行駛時，其最大脫軌係數為0.89，發生在曲率半經85 m的彎道上，最大輪重減載率為0.36，發生在曲率半徑240 m的彎道上。

In this thesis, a rigid-flexible coupling model of a light rail vehicle is proposed for the simulation of dynamic performance and traction performance. The model combines the multi-body dynamic software SIMPACK and the dynamic simulation software SIMULINK. Firstly, the multi-body dynamic model and traction system model of the MRT railway vehicle is proposed. The simulation results are compared with the results obtained from the actual MRT vehicle to confirm the accuracy of the proposed dynamic model. Then, the multi-body dynamic model and traction system model of the light rail vehicle is established to simulate the dynamic performance and the traction motor performance.
The results show that the total energy consumption of the traction motor obtained from the simulation of the MRT railway vehicle is 247 kWh. The difference between the simulation and the actual motor power is 5%. The accuracy of the proposed model is confirmed. In addition, the required motor torque and power of the light rail vehicle obtained from the proposed dynamic model are 674 N-m and 63 kW, respectively. In this study, the maximum derailment coefficient is 0.89, which occurs on a curve with a curvature radius of 85 m, and the maximum wheel load reduction rate is 0.36 occurred on a curve with a curvature radius of 240 m.
