近代振动隔离技术的发展受到两方面的推动,一是噪声控制的呼声日益高涨,促使从事振动工程的人深入研究噪声发生的机理,固体声幅射特性以及非刚性系统的隔振等,另是高频声振动的危害已成为航天、航空工程中不可忽视的严重障碍,从而激励人们去寻求具有宽频带抑制特性的隔振器材,这促进了粘弹性阻尼材料、双层隔振装置以
In recent years, the development of vibration isolation technology has been promoted by two aspects. One is the growing noise of noise control, prompting people engaged in vibration engineering to deeply study the mechanism of noise generation, solid acoustic radiation characteristics and vibration isolation of non-rigid systems. The harm of high-frequency acoustic vibration has become a serious obstacle that can not be ignored in aerospace and aeronautical engineering, so as to encourage people to seek vibration isolation equipment with wideband suppression. This promotes the development of viscoelastic damping materials,
