双层隔振系统隔振效果研究

Study on the vibration-isolation effect of double--stage vibration-isolation systems

隔振系统的隔振效果与被隔离体、中间质量块及基座中的弹性模态有很大的关系.在考虑被隔离体、中间质量块及基座为弹性体的前提下,研究了它们的弹性模态对系统隔振效果的影响,得出了设计隔振系统时要遵循的一些原则.

There exists close relation between the vibration\|isolation effect and the elastic modes of the isolated equipment, the middle mass block and the ship mounting base. On condition that the isolated equipment α, the middle mass block β and the ship mounting base γ are all elastic bodies, this paper studied the affectionof the elastic modes of α?β?and γ on the vibration\|isolation effect of the system, and presented some principles which should be followed while designing vibration\|isolation system.
