SHOCK ABSORBER FOR AN OBJECT PLACED IN A MEDIUM SUBJECTED TO VIBRATIONS AND CORRESPONDING SHOCK ABSORBER SYSTEM

摘要

A damper for an object is placed in a medium subjected to vibrations. The damper has an idle state in the absence of vibrations, a first operating state in case of vibrations of a first type, and a second operating state in case of vibrations of a second type. The level of each vibration of the first type is less than the level of each vibration of the second type. The damper includes an outer support structure, an inner support structure, and at least one pair of membranes formed of a first membrane and a second membrane. Each membrane is formed of a viscoelastic material including fibers aligned substantially in a same direction.
