broad band random vibration

基本解释

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.
本文在某支撐座結搆模型寬帶隨機振動實騐的基礎上，研究了如何監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結搆許多諧振峰，利用粘彈阻尼技術隔振、減振和降噪是一項新的技術措施，尤其是對於寬帶隨機振動和噪聲控制具有特殊傚果。
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.
