Title:
防振構造
Document Type and Number:
Japanese Patent JP7355627
Kind Code:
B2
Abstract:
To provide a vibration isolation structure which can reduce a high-vibration frequency component caused by impact excitation such as a jump while remarkably lowering reaction magnification in a specified vibration frequency region.SOLUTION: A vibration isolation structure has; a structure; a first support spring (first spring element) arranged on the structure; a first floating floor (first vibration body) arranged on the structure via the first support spring; a second support spring (second spring element) arranged on the first floating floor; a second floating floor (second vibration body) arranged on the first floating floor via the second support spring; and an inertia mass device arranged between the first floating floor and the second floating floor in parallel with the second spring element. A mass of the first floating floor is set equal to a mass of the second floating floor or higher, the spring stiffness of the first support spring is set lower than the spring stiffness of the second support spring, and the inertia mass device is set as the following formula. [Numerical formula 1].SELECTED DRAWING: None
