Abstract
The utility model discloses a positive and passive composite vibration isolator which is provided with a magnet-insulated bottom seat. The upper part of the magnet-insulated bottom seat is provided with a magnet-insulated upper cover; the lower surface of the magnet-insulated upper cover and the upper surface of the magnet-insulated bottom seat are separately provided with an electromagnet and a permanent magnet both of which take the shapes of a flat plate and have the same shape, relevant upper part and lower part and rigid elements around. The upper end and the lower end of the rigid element are separately fixed on the lower surface of the magnet-insulated upper cover and the upper surface of the magnet-insulated bottom seat; the height of the rigid element during non-work state is larger than the thickness of the electromagnet plus the thickness of the permanent magnet and the stroke of the magnet-insulated upper cover, thus makes a spacing formed between the electromagnet and the permanent magnet. The positive and passive composite vibration isolator has a good vibration isolation effect and is suitable for the vibration isolation in cars, ships, aircrafts and all mechanical equipment.
Description
(1) technical field
The utility model relates to a kind of vibration damping equipment.Specifically, be to have electromagnetic suspension vibration isolator main, passive complex function, be applicable to the vibration isolation of automobile, naval vessel and aircraft and various machinery.
(2) background technique
On the traffic tool such as automobile, naval vessel and aircraft and various machinery, used vibration isolator all is pure machinework, has only the passive vibration isolation function at present.And the various traffic tool and machinery travel or running in, all can occur bigger random load variation or operating conditions unavoidably changes, this just requires used vibration isolator to have self parameter adjustment function, to adapt to when occurring still having vibration isolating effect preferably when big random load or operating mechanism operating mode change.Because traditional vibration isolator is pure machinework, have only the passive vibration isolation function, in case make, himself parameter just can not be adjusted.Become big or machinery operating conditions when changing when random load appears in the traffic tool, vibration isolating effect is relatively poor, and especially the low frequency vibration isolation effect is just poorer.
(3) model utility content
Problem to be solved in the utility model provides a kind of master, passive combined type vibration isolator.This master, passive combined type vibration isolator, vibration isolating effect is better.
For addressing the above problem, the utility model is taked following technological scheme:
Master of the present utility model, passive combined type vibration isolator characteristics are to contain exhausted magnetic base, and there is exhausted magnetic loam cake exhausted magnetic base top, on the exhausted magnetic loam cake lower surface and on the exhausted magnetic base upper surface electromagnet and permanent magnet is arranged respectively.Said electromagnet and permanent magnet are planar, the identical and upper and lower correspondence of their shape, and there is stiffness elements their outside.The upper and lower end of stiffness elements is separately fixed on the upper surface of exhausted magnetic loam cake lower surface and exhausted magnetic base, its height when off working state forms spacing greater than the stroke sum of electromagnet thickness, permanent magnet thickness and exhausted magnetic loam cake thereby make between electromagnet and permanent magnet.
Take such scheme, have the following advantages:
Because master of the present utility model, passive combined type vibration isolator contain exhausted magnetic base, there is exhausted magnetic loam cake exhausted magnetic base top, on the exhausted magnetic loam cake lower surface and on the exhausted magnetic base upper surface electromagnet and permanent magnet is arranged respectively.There is stiffness elements the outside of electromagnet and permanent magnet.The upper and lower end of stiffness elements is separately fixed on the upper surface of exhausted magnetic loam cake lower surface and exhausted magnetic base, and its height when off working state forms spacing greater than the thickness sum of electromagnet and permanent magnet thereby make between electromagnet and permanent magnet.The electromagnetic suspension mechanism that employing is made up of electromagnet and permanent magnet is as the active vibration isolation unit, and after its structure and major parameter were determined, the size of its active controlling force, direction and frequency were just decided by size, direction and the frequency of magnet control electric current fully.When being used for the traffic tool, can adjust the size of magnet control electric current according to the size of random load, adapt to of the requirement of big random load, thereby improve vibration isolating effect, especially low frequency vibration isolation effect greatly vibration isolator.
(4) description of drawings
Accompanying drawing is master of the present utility model, passive combined type vibration isolator structural representation.
(5) embodiment
As shown in drawings, master of the present utility model, passive combined type vibration isolator contain exhausted magnetic base 5 and exhausted magnetic loam cake 1, and the shape of this exhausted magnetic base and exhausted magnetic loam cake is identical, size is identical and be planar, are the parellel layout between the two.Be fixed with electromagnet 2 and permanent magnet 4 respectively on exhausted magnetic loam cake 1 lower surface and on exhausted magnetic base 5 upper surfaces, this electromagnet and permanent magnet also are planar, the identical and upper and lower correspondence of their shape, and their outside is with stiffness elements 3.Said stiffness elements 3 is metal spring (also can adopt rubber spring), its upper and lower end is separately fixed on exhausted magnetic loam cake 1 lower surface and cuts off on the upper surface of magnetic base 5, its height when off working state is greater than the stroke sum of the thickness and the exhausted magnetic loam cake 1 of the thickness of electromagnet 2, permanent magnet 4, thereby makes 4 formation of electromagnet 2 and permanent magnet spacing.
When no current in the electromagnet 2 passed through, master of the present utility model, passive combined type vibration isolator were the passive type vibration isolator.And when having electric current to pass through in the electromagnet 2, the utility model is main, passive combined type vibration isolator.
Claims (3)
1. main, passive combined type vibration isolator is characterized in that containing exhausted magnetic base (5), and there is exhausted magnetic loam cake (1) exhausted magnetic base (5) top, on exhausted magnetic loam cake (1) lower surface and on exhausted magnetic base (5) upper surface electromagnet (2) and permanent magnet (4) is arranged respectively; Said electromagnet (2) and permanent magnet (4) are planar, the identical and upper and lower correspondence of their shape, and there is stiffness elements (3) their outside; The upper and lower end of stiffness elements (3) is separately fixed on the upper surface of exhausted magnetic loam cake (1) lower surface and exhausted magnetic base (5), its height when off working state forms spacing greater than the thickness of electromagnet (2), the thickness of permanent magnet (4) and the stroke sum of exhausted magnetic loam cake (1) thereby make between electromagnet (2) and permanent magnet (4).
2. master according to claim 1, passive combined type vibration isolator is characterized in that said stiffness elements (3) is a metal spring.
3. master according to claim 1, passive combined type vibration isolator is characterized in that said stiffness elements (3) is a rubber spring.
