軸向振擺 的英文怎麼說
中文拼音 [zhóuxiàngzhènbǎi]
軸向振擺
英文
planlauf axial runout-
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。By using the method of transfer matrix, the dynamic model of the driving shaft vibration of swing movable teeth reducer is built. the calculation formula for natural frequencies of the flexural vibration of the driving shaft is derived
應用傳遞矩陣法,建立了擺動活齒減速器輸入軸振動的動力學模型,導出了輸人軸橫向彎曲振動的固有頻率的計算公式。Furthermore, the " mass - spring " system formed by the sleves and the springs, was regularly oscillating at it natural axial frequency, generating vibrations
而且,由軸套向彈簧所組成的「質量彈簧」系統會以其自然的軸向頻率發生有規律的擺動,並導致振動現象的出現。
