軌道列車不同行駛條件之車外噪音量測實例與成因探討
Discussion The Causes of Railbound Vehicle with Different Driving Conditions by the Noise Measurement Examples
摘要
本文首先研析國際標準化組織ISO 3095軌道車輛散播噪音源之量測、行政院環保署「陸上運輸系統噪音量測方法」及「陸上運輸系統噪音管制標準」等三項標準規範。再依循上述標準之原則、方法及要求，考量測試標的之營運場域、行駛條件及其他相關測試參數，制定測試程序與量測方法，並實際挑選國內日常運轉中之捷運車輛完成車外噪音量測。而在文末分別探討該捷運車輛在空車靜止無行駛、營運速度行駛以及加速減速行駛狀態下之噪音成因，最後依據「陸上運輸系統噪音管制標準」內規範之軌道系統平均最大音量（L_(max,mean)），和不同行駛條件之量測結果進行比對，確保噪音值之合理性。

This research first analyzes three standard of ISO 3095 Measurement of noise emitted by railbound vehicles, "land transportation system noise measurement method" and "land transportation system noise control standard". According to the principles, methods and requirements of the above standards, consider the operating field, driving conditions and other relevant test parameters of the test target, formulate test procedures and measurement methods, and actually select the MRT vehicles in daily operation in Taiwan to complete the noise measurement. In the end of this research, the noise causes of the railbound vehicles in the idle, non-driving, operating speed and accelerated deceleration modes of the empty vehicles are discussed respectively. Finally, the average maximum volume of the orbital system (L_(max,mean)) is specified according to the "land transportation system noise control standards". In order to ensure the reasonableness of the noise value, compared the measurement results of different driving conditions indispensable.
