VIBRATION INSULATING DEVICE, ASSOCIATED SHOCK ABSORBER AND USE OF SAID SHOCK ABSORBER

摘要

The invention relates to a vibration insulating device of at least one apparatus on board a supporting structure including first and second rigid portions (11, 12) and at least two resilient elements connected in series, each of the resilient elements having different stiffnesses, one of the rigid portions being intended for being attached to the apparatus and the other to the supporting structure, a first element (13) being attached to the first rigid portion and a second element (14) being attached to the second rigid portion (12); there is a range of deformation values in which the first resilient element (13) has a rising stiffness and the second resilient element (14) has a stiffness which is substantially constant in accordance with the deformation applied, said stiffness of the first resilient element being lower than that of the second resilient element in a lower portion of said range and higher in an upper portion of said range.
