Description
Technical field
The present invention relates to vibration isolating mechanism in vibrational system, more specifically a kind of paralleling model semi-active vibration-isolating device suitable in automobile power assembly suspension system, naval vessels dynamical system, medical instrument system, special equipment vehicle, machine tooling equipment etc. with rotating machinery power system.
Background technology
Rotating machinery is to apply power output element widely in engineering field, in the use procedure of rotating machinery, is usually present the disturbance excitation changed with they rotation speed change.For internal combustion engine, when internal combustion engine, the pitching moment that cylinder pressure and reciprocal inertia force produce is the major disturbances excitation of internal combustion engine, and perturbing torque frequency is the twice of internal-combustion engine rotational speed angular frequency, if such disturbance is passed directly to matrix, the high vibration of matrix can be caused.For reducing vibration, vibration isolation element can be set between rotating machinery and matrix, if but vibration isolation element design is unreasonable, also the vibration of even severe exacerbation body can be easily caused, the damage of aggravation associated mechanical electronic unit, shorten their service life, therefore that the design of rotating machinery vibration isolation element is particularly significant.Traditional rotating machinery vibration isolation element generally uses rubber mounting, the rigidity of rubber mounting just has determined that at the beginning of being typically in engineering design, the anti-vibration performance of suspension members should be considered during due to design suspension members rigidity, take into account requirement that is rotating machinery is spacing and that support again, therefore when design, the rigidity of suspension members unavoidably can be bigger than normal to some extent, this natural frequency allowing for suspension system is bigger than normal, therefore under rotating machinery slow-speed of revolution operating mode, the driving frequency of rotating machinery vibrating is close to the natural frequency of suspension system, cause the serious vibration of rotatory mechanical system, have impact on the normal use of associated components.
Consider that vibration isolation element to meet spacing requirement on the one hand, also to play the function of isolation rotating machinery vibrating on the other hand, therefore in engineer applied, in order to reduce the vibration that rotatory mechanical system causes, the desirable dynamic stiffness characteristic of vibration isolation element should be that low frequency has high dynamic stiffness, high frequency has low dynamic stiffness, and such vibration isolation element just can play during low frequency spacing, the function of vibration isolation during high frequency.But current passive Rubber Isolators dynamic stiffness characteristic has low dynamic stiffness when being low frequency, there is during high frequency high dynamic stiffness, the dynamic stiffness characteristic contrast of this and desirable vibration isolation element, therefore anti-vibration performance is being required on higher rotating machinery, the ability of Rubber Isolators isolation vibration is just extremely limited, the vibration easily making rotating machinery is delivered to matrix, the damage of aggravation related components.
For making the dynamic stiffness characteristic of vibration isolation element meet the characteristic of desirable low frequency high dynamic stiffness and the low dynamic stiffness of high frequency, generally having two schemes optional: one is the damping characteristic changing vibration isolation element, two is the Static stiffness characteristic changing vibration isolation element.For the first scheme, it is designed as example with engine mounting, the magnetorheological hydraulic mount that Chinese scholars proposes can play the effect well improving suspension damping, Jiangsu University land dawn et al. has applied for the patent of invention of a kind of mixed model magnetorheological hydraulic mount, number of patent application is CN201310629286.5, the magnetorheological hydraulic engine mount of this application for a patent for invention adopts the extruding of magnetic flow liquid and the mode of operation of flowing immixture, change the vibration isolation capability of suspension system by changing the viscous damping of magnetic flow liquid, good effectiveness in vibration suppression can be played.For first scheme, the dynamic stiffness characteristic of vibration isolation element can be changed by changing the Static stiffness characteristic of vibration isolation element, the final resonant frequency changing vibrational system, make the resonant frequency driving frequency away from rotating machinery of rotatory mechanical system, based on this principle, it is possible to design the use rigidity controlled element element with variable rigidity as vibration isolator.Magnetic rheology elastic body as a kind of novel intellectual material, due to its have rigidity continuously controlled, without encapsulation, lower-cost advantage, the shortcoming overcoming again magnetic flow liquid free settling, poor stability, be therefore highly suitable as the rigidity controllable element of vibration isolator.But owing to the load of rotating machinery is general all bigger, if directly magnetic rheology elastic body is born the load of rotating machinery as vibration isolation element, tend to exceed the yield strength limit of magnetic rheology elastic body, easily cause the damage of magnetic rheology elastic body, and the stiffness variation of the magnetic rheology elastic body being independently operated under shear mode or squeeze mode is limited in scope, the shift frequency making vibration isolation element is limited in scope, and this all limits magnetic rheology elastic body application on the vibrational system vibration isolation technique that load is bigger to a certain extent.
Summary of the invention
The present invention is the deficiency avoiding above-mentioned prior art to exist, it is provided that a kind of paralleling model semi-active vibration-isolating device.Operation principle according to vibration isolator, magnetic rheology elastic body semi-active control technology is applied in rotating machinery vibrating isolation system, the dynamic stiffness characteristic making vibration isolation element meets desirable low frequency high dynamic stiffness, the characteristic requirements of the low dynamic stiffness of high frequency, reduce the vibration of rotatory mechanical system, reduce the vibration of rotating machinery related components, improve their service life.
