Vibration isolation - Wikipedia

Vibration isolation is the process of isolating an object, such as a piece of equipment, from the source of vibrations.. Vibration is undesirable in many domains, primarily engineered systems and habitable spaces, and methods have been developed to prevent the transfer of vibration to such systems.

Vibration Engineering - Basics

The vibration isolation of a dynamic system consists of isolating from the environment by means of an elastic body which has a considerably lower natural frequency f 0 than the system forcing frequency f E.. Figure 2 schematically shows such a system with isolation. Of practical interest is the transmitted force F R output and the ratio of this force to the original input force.

VIBRATION IN HEAT EXCHANGERS - Thermopedia

In calculating tube vibration, it is important to find the natural frequency of vibration of the tubes. For a tube with pivoted ends vibration may occur according to mode shapes 1,2, and 3 as shown in Figure 2.The natural frequency of vibrations depends on both the mode shape and the physical characteristics of the tube, and the way its ends are fixed; it can be calculated by the formula
