摘要:牽引電動機是電動機的類型之一,用于驅動電力機車、內燃機車、電動車輛、工礦機車、地下鐵道車輛、城市電車及公路車輛等運行的主電動機,它的運行性能直接影響機車車輛的牽引性能及經濟技術指標。牽引電機是牽引電機車的關鍵零部件,而牽引電機特性測試平臺是評估電驅動系統性能的有效手段。牽引電機車在行駛過程中,電驅動系統必須滿足頻繁的加速和減速(爬坡)、多次怠速、以及速度的隨機變化。因此,在測試平臺上再現車輛行駛工況以及設計牽引電機特性測試平臺是十分必要的。本論文參考國內外眾多牽引系統,按照硬連接方法采用一臺電機帶另一臺電機進行牽引電機車電機特性測試平臺的仿真。分析了電回饋加載系統的控制策略以及工作原理,并通過仿真軟件建立了相應的仿真模型運用MATLAB/SIMULINK 進行了仿真研究,在理論上論證了系統的可行性;采用矢量控制算法設計交流牽引電機車變頻調速系統并進行仿真,實驗工況有輕載、滿載、超載三種,得到了不同工況下的實驗數據。實驗還可以進行負載加載實驗,得出了負載轉矩與牽引電機轉速之間的關系。34261

Design of Traction electric locomotive motor characteristics simulation test platform
Abstract:Traction motor is one type of motor for driving the run electric locomotives, diesel locomotives, electric vehicles, mining locomotive, underground railway vehicle, urban tram and road vehicles such as the main motor, its performance directly affects the performance of traction and rolling stock economic and technical indicators. Traction motors is the traction motor vehicle key components, and the traction motor characteristics of the test platform is an effective means of assessing the performance of the electric drive system. Traction motor vehicle during driving, the electric drive system must meet the frequent acceleration and deceleration (climbing), idle times, and a random speed changes. Therefore, on the test bench reproducing driving conditions and vehicle traction motor design characteristics of the test platform it is necessary. In this paper, with reference to foreign and domestic traction system, according to the hardwired method uses a motor with another motor vehicle traction motors motor characteristics simulation test platform. The vector control algorithm AC traction motor vehicle frequency control system and simulation, experiment with light load conditions, full load, overload of three, the experimental data obtained under different conditions. You can also load test load experiments, the relationship between the load torque between the motor speed and traction. 源`自*六)維[論*文'網www.mmeqir.tw
