Low friction coefficient between pcd diamond and steel materials reduces frictional resistance during bearing processing, thus enhances bearing processing precision
Pcd金剛石和鋼鐵材料的磨擦系數低、減少了軸承加工的磨擦阻力,提高了軸承的加工精度。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。
