Vibration isolation
Frequently asked questions (FAQ)
Structure-borne sound insulation, also called vibration insulation, is a vibration insulation for frequencies above 40-50 Hz. It reduces the transmission of structure-borne sound which is emitted by machines or equipment and spreads in solid bodies (steel girders, concrete floors etc.) and is disturbingly radiated as airborne sound.
Vibration damping is the conversion of mechanical kinetic energy of a vibrating system into another form of energy, e.g. heat.
Vibration isolation or vibration reduction can be achieved by elastic and damping elements to reduce the forces from a machine or the vibrations transmitted from the environment to a machine, if certain forces are applied to a machine or device and these are supported on elastic and damping elements thereby reducing the transmission of these forces to the environment. This type of vibration insulation is called source insulation and active vibration insulation. If a building or a machine is supported on elastic and damping elements in order to reduce the ground displacements which act as foot point excitation from the system to be protected, this type of vibration insulation is called receiver insulation of a passive vibration insulation.
A vibration damper is a system for damping mechanical vibrations such as shocks, vibrations, shocks, etc. The primary goal of a vibration damper is to convert kinetic energy into thermal energy.
Moving parts on machines, equipment, apparatus and vehicles generate vibrations and noise. They are caused by uneven or rotating movements of unbalanced masses. Vibrations and shocks act as vibrations and noise disturb the environment.

Vibration isolation as active or passive isolation. The basic principle of vibration isolation is to separate the disturbing object (active isolation) or the object to be protected (passive isolation) from each other and to expand isolation materials or rubber satellite elements or springs into a system capable of vibration by means of an intermediate layer. The principle of vibration suppression consists in the fact that by frequency tuning from the excitation frequency to the natural frequency, the movements are no longer synchronous with the interference, but in opposite phase to it.
