broad band random vibration

基本解釋

Based on the broad-band random vibration test on a clamping support in missiles, this paper investigates the problems on evaluating the attachment bolt looseness in the structure.
本文在某支撐座結(jié)構(gòu)模型寬帶隨機振動實驗的基礎(chǔ)上，研究了如何監(jiān)測連接螺釘組松動故障程度的問題。
The noise from Broad Band random vibration strike causes many syntony peak of structure. The insulating and reducing vibration and noise by viscoelastic damp material is a new technology measure.
寬頻帶隨機振動沖擊噪聲會激發(fā)結(jié)構(gòu)許多諧振峰，利用粘彈阻尼技術(shù)隔振、減振和降噪是一項新的技術(shù)措施，尤其是對于寬帶隨機振動和噪聲控制具有特殊效果。
Three methods, i. e. experimental attenuation model, random vibration method and broad band Green function method for strong ground motion prediction were also summarized and reviewed in this paper.
