The present invention discloses a self-adaptive equal rigidity vibration isolator based on air floatation and electric combination three-dimensional decoupling, and mainly relates to the three-dimensional equal rigidity active vibration isolation field of electronic equipment. The self-adaptive equal rigidity vibration isolator comprises a three-dimensional moving block installed in a vibration isolation housing, a vibration isolation pole installed at an upper portion of the three-dimensional moving block, a vibration isolation platform installed at an upper end of the vibration isolation pole, air floatation damping systems and electric damping systems; and the air floatation damping system is installed in at least one of the X, Y and Z directions, and the electric damping system is installed in at least one of the X, Y and Z directions. The self-adaptive equal rigidity vibration isolator based on air floatation and electric combination three-dimensional decoupling is reasonable in structure, air floatation and electric are combined, three-dimensional rigidity is decoupled, and the rigidity is actively adjusted.
Description
technical field [0001] The invention mainly relates to the field of three-way equal-stiffness active vibration isolation of electronic equipment, in particular to an adaptive equal-stiffness vibration isolator based on three-way decoupling of air flotation and electric combination. Background technique [0002] In the three-way vibration isolation of electronic equipment, traditional vibration isolation equipment mainly includes wire rope vibration isolators, metal spring vibration isolators, harmonic-free vibration isolators, rubber vibration isolators, etc. These vibration isolation devices all have certain defects, that is, they cannot realize vibration isolation with equal stiffness in the three directions of X, Y, and Z. [0003] In the prior art, a three-way equal stiffness metal vibration isolator (patent number: 201210449640.1) realizes vibration isolation with equal stiffness in X, Y, and Z directions through six compressed coil springs arranged on the protruding sh...
