本文主要是从振动原理上分析带有阻尼的二自由度系统的振动的隔离问题,也就是从理论上探讨仪器与安装支架之间的合理设计问题。本文对二自由度粘性阻尼系统的振动传递率的表达式进行数学推导,并以 VAX—780机的计算数据和绘制的相应的曲线,阐明如何选择系统的参变量,以实现良好的所期望的隔振性能。本文也试图说明这个问题的重要性,以期引起足够的重视。
In this paper, we mainly analyze the vibration isolation of a two-degree-of-freedom system with damping from the principle of vibration, that is, to theoretically explore the reasonable design problem between the instrument and the mounting bracket. This paper mathematically deduces the expression of the vibration transmissibility of two-degree-of-freedom viscous damping system and illustrates how to choose the parameters of the system based on the calculation data of VAX-780 and the corresponding curve drawn in order to achieve good expected Vibration isolation performance. This article also attempts to illustrate the importance of this issue with a view to attracting enough attention.
