Abstract

The invention relates to a variable friction damping vibration isolator with an adjustable central position, and belongs to the field of vibration isolators of electronic equipment. The problem that the vibration isolation capacity of the vibration isolator on a high-frequency vibrating load is weakened due to the fact that an existing vibration isolator cannot adjust the central position of variable friction damping, and when loaded actual weight is different from rated bearing capacity of the vibration isolator, the vibration center of the vibration isolator is deviated from the central position of low-friction damping force of a damping spring piece is solved. The variable friction damping vibration isolator comprises a base, a clamping spring, friction guide rails, an upper cover, a loading installation seat, friction pressure springs, friction heads and a main isolation spring; and the friction guide rails are matched with the clamping spring through a friction guide rail height adjustment conical surface, and the upper cover covers the friction guide rails. According to the variable friction damping vibration isolator with the adjustable central position, by adjusting pretightening force of the upper cover, the central positions of the friction guide rails can move up and down, and the central position of the variable friction damping vibration isolator is adjusted.

Description

technical field [0001] The invention relates to a variable friction damping vibration isolator with adjustable center position for electronic equipment, in particular to a vibration isolator for electronic equipment such as electronic cabinets that are subjected to long-term vibration loads (such as vehicle-mounted and airborne). Background technique [0002] The vibration isolator based on variable friction damping has good high frequency and low frequency vibration isolation effect due to high low frequency damping and low high frequency damping, so it is used in the field of vibration isolation of electronic equipment such as electronic cabinets. very broad. [0003] The friction pair of the existing dry friction type vibration isolator usually uses a set of variable curvature spring pieces and friction blocks to provide dry friction damping. The variable curvature spring pieces have large curvature at the vibration center position and small curvature at both ends; when t...
