阻尼踏板 的英文怎麼說
中文拼音 [zǔnítàbǎn]
阻尼踏板
英文
damper pedal-
Then according to the demand of the wheel damper and the characteristic of the tread vibration and the web vibration, a new type of wheel damper was designed and produced
再次,根據車輪阻尼器的設計要求,結合車輪踏面和輻板振動的特點,設計了新型車輪阻尼器。We did some analysis about the relativity between the vibration and the noise of the wheel. after the testing of the first line of guangzhou underground, we found that the existing wheel damper has nothing to do with the noise of wheel less than four thousands hz. compared of different contributions of the tread vibration and the web vibration on sound level of railway noise
在實驗過程中,改進了對車輪的激振方式,利用單擺激振提高了激振力的精度;實驗分析了車輪阻尼器的結構、安裝方式及其動力學參數對車輪阻尼器降噪效果的影響;也分析了車輪振動與噪聲的相關性;現場測試廣州地鐵一號線的噪聲特性,確定了車輪阻尼器所要控制的頻率范圍;對比分析不同激振情況下,踏面徑向振動與輻板軸向振動對噪聲聲壓級的貢獻比例。
