By definition, damping is the ability of a vibrating structure or system to dissipate energy. If the dissipation is through internal friction caused by molecular structure, it is called material damping. On the other hand, when it is produced by friction, rubbing and impacting at the joints of a structural assembly, it’s referred to as structural damping. In most applications of vibration, the magnitude of damping forces is small when compared to the inertia and elastic forces. However, under special circumstances these small damping forces can have great impact or influence in controlling the level of vibration.
They are executed through devices called vibration damper. These anti-vibration devices are very important in controlling vibration response amplitudes. They also play a significant role in addressing a critically thin line between stability and instability in dynamic machinery and systems. A vibration damper is also very crucial in controlling vibration under conditions of stationary random excitation. To better understand why this tool is of utmost importance, it’s good to know what is behind the phenomenon of vibration, which is the cyclic oscillation. It refers to the cyclic transformation of the potential energy into kinetic and then back again.
This can be clearly displayed by elastic and inertial idealized models. For instance, the natural frequencies and modes of vibrating systems are obtained from those models. Considering a vibration damper happens in the secondary aspect of oscillation dynamics. This damping mechanism removes the energy from the system. And eventually, damping results to the final decay of free vibrations. If your business would benefit from the use of vibration damper and other anti-vibration solutions, shock control or noise reduction products, VibraSystems is the leading designer and manufacturer of these products. In addition to our stock products, we also specialize in custom design and product development according to your specific vibration control requirements with our in-house engineering team.
