機場捷運電聯車轉向架穩定性測試簡介 Introduction to the TIAA MRT EMU Bogie Stability Test

本測試標的為機場捷運電聯車(4車廂)普通車及(5車廂)直達車,先後均載以空重(W0)及結構設計載重(W3)後,分別以時速60、70、80、90及100 km/h之速度,於主線上穩速操作列車(如圖2車輛行駛曲線圖),並於轉向架及列車上設置「位移計」、「資料記錄器」及「頻率 – 電壓(F/V) 轉換器」等測試儀器,量測轉向架之旋轉振幅及頻率值,且同時超過規定數值之情形,不得連續超過20個波形。

The purpose of this test is to ensure that the train can continuously retain dynamic stability and will not experience hunting under operation speed (100km/h), various weight loads and different track conditions. When the train is operating under high speed and the wheel-set continues to swing and fails to return to a stable state, hunting occurs.
The targets of this test are the 4-car Commuter EMU and the 5-car Express EMU of TIAA MRT. The coaches were tested at 60, 70, 80, 90 and 100 km/h respectively with tare weight (W0) and structural designed load (W3) on the main line (see figure 2). The bogies and coaches are equipped with displacement sensors, recorders and frequency/voltage converters to measure the swinging amplitude and frequency of the bogie and should not over the regulation values simultaneously over 20 hunting waves.
This stability test is scheduled to execute in the second half of 2014 between Kengkou Station (A11) Station and Taiwan Taoyuan International Airport Terminal 1 (A12) Station. BOHSR will continue to supervise contractors to accurately execute the test to ensure operation safety.
