DamperX™ Technology | Vibration, dynamics and noise

With low-damped systems, the vibration ringdown time after the initial event can be severely long. Damping is a proven solution to control vibration and is used extensively in the automotive and aerospace industries (think of the shocks in your car). A DamperX vibration-damping pipe clamp or brace adds significant damping to the system. The ...

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
