Close electronic equipment, realizes superlow frequency vibration isolating, and designing a kind of ultralow frequency resonance-free vibration isolator has important practical value.
The content of the invention
The technical problem that the present invention need to be solved is：For prior art exist system frequency is higher etc. that technology is asked
Topic, the present invention provide a kind of ultralow frequency resonance free metal rational in infrastructure, that good vibration isolation can be realized to low-frequency excitation signal every
Shake device.
In order to solve the above problems, solution proposed by the present invention is：A kind of ultralow frequency resonance free metal isolator, bag
Vibration isolation guide pillar is included, the vibration isolation plate of the vibration isolation guide pillar upper end is installed in, is installed in the free plate of the vibration isolation guide pillar lower end, hollow
Cylinder, the shaft bearing plate for being installed in the hollow cylinder upper end, the fixed plate for being installed in the hollow cylinder lower end, be installed in it is described
Butterfly spring B in fixed plate and inside the hollow cylinder, it is installed in the bottom of the shaft bearing plate and positioned at the sky
The butterfly spring A of heart cylindrical inside；Protected vibration isolation object is equiped with the vibration isolation plate；The free plate is located at the butterfly
Between shape spring A and the butterfly spring B；The lower end of the vibration isolation guide pillar passes through the linear axis being installed on the shaft bearing plate
Hold.
Butterfly spring A of the invention, the pressure of the butterfly spring B are two sections of skew lines with quiet deformation curve, wherein
The slope of second segment skew lines is about 1st/20th of first paragraph skew lines slope；It is oblique in the second segment of the butterfly spring B
In straight line, maximum distortion is S2, and minimal deformation is S1, and S1 is 1/3rd of S2；The butterfly spring B is in the vibration isolation thing
Deformation under body Action of Gravity Field is S1, and the butterfly spring A is connectionless with the free plate；Shown in the vibration isolation object is installed in
After on vibration isolation plate, the deformation of the butterfly spring B is whole to be on the pressure with the second segment skew lines of quiet deformation curve
The intrinsic frequency of system is 2-3Hz.
The present invention compared with prior art, has the following advantages that and beneficial effect：
(1) a kind of ultralow frequency resonance free metal isolator of the invention, using the butterfly spring A and butterfly spring of diclinic rate
B, after vibration isolation object is installed, butterfly spring B deformations are located on second segment skew lines, therefore system is operated in the second slope straight line
Section, system frequency is relatively low.
(2) the butterfly spring B in a kind of ultralow frequency resonance free metal isolator of the invention, the slope of first paragraph straight line is about
It it is 20 times of second segment straight slope, the intrinsic frequency in the whole system course of work is 2-3Hz.It follows that of the invention
Superlow frequency vibration isolating can be realized, so as to improve vibration isolating effect of the dynamic excitation in 5-10Hz.
