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 Vibrations propagate via mechanical waves and certain mechanical linkages conduct vibrations more efficiently than others Passive vibration isolation makes use of materials
