Title:
VIBRATION-ISOLATING MECHANISM
Document Type and Number:
Japanese Patent JP2018096513
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a vibration-isolating mechanism capable of suppressing an excessive response at a resonance point while securing vibration isolation performance in a high-frequency range by reducing attenuation.SOLUTION: A vibration-isolating mechanism 1 for reducing a reaction force acting on a structure floor 11 when a floating floor (vibrating body) 12 installed on the structure floor (structure) 11 via a support spring element 13 is excited has an additional spring element 14 which is installed in parallel with the support spring element 13 between the structure floor 11 and the floating floor 12 and which acts when an absolute value of relative displacement of the structure floor 11 and the floating floor 12 reaches a predetermined value or above.SELECTED DRAWING: Figure 1
