Description
Technical field
What the present invention relates to is a kind of bump leveller, specifically a kind of dynamic vibration absorber of variable rigidity.
Background technique
Mechanical vibration can cause numerous adverse influences in engineering, as cause noise pollution, affect the work of other machinery, reduce the precision of instrument, machine, when serious, even can cause the destructions such as equipment, building structure.In engineering, use multiple means to reduce the harm of vibration, mainly contain absorbing, vibration isolation, resistance is shaken, weakening and structural modification etc.Wherein in controlled system, additional power bump leveller is to suppress the effective means of vibration.Dynamic vibration absorber is a kind of certain rigidity that has, the structure of quality.When thering is the excitation source of characteristic frequency total system encouraged, if the natural frequency of bump leveller is identical with excited frequency, cause the resonance of bump leveller, make the energy of its absorption maximum.When excitation source inputs to total system constant in energy, the energy of controlled device input is minimum, makes the vibration of controlled device under this frequency minimum, plays the effect of absorbing.
And traditional dynamic vibration absorber is rigidity, the system of the immutable passive types of parameter such as quality, natural frequency can not regulate constantly, and the characteristic frequency of controlled system is had to good shock attenuation result, but the shock attenuation result of the object that vibration frequency is changed is poor.Therefore in vibration engineering field, usually design the adjustable semi active vibration absorber of some parameters, be called again self-tuning bump leveller.Conventionally adopt the method that becomes rigidity to regulate absorbing frequency, as realized the change of rigidity by electrorheological fluid or magnetic flow liquid, ([1] Liao Guojiang, Gong Xinglong, Xuan Shouhu, Kang Cunjun. the research [A] of the active self-tuning dynamic vibration absorber based on magnetic rheology elastic body. the 6th national emr fluid and application academic conference program volume and thesis summary set [C] .2011), by changing gap, regulate ELECTROMAGNETIC STIFFNESS, ([2] Qian little Yong, Hu Haiyan. the semi active vibration absorber of adjustable clearance and realization thereof [J]. vibration engineering journal, 2001, 14 (4): 378-382), change spring rate number of active coils ([3] Xu Zhenbang, Gong Xinglong, Chen Xianmin etc. mechanical type frequency is adjustable dynamic vibration absorber and damping behavior thereof [J]. vibration with impact, 2010, 29 (2): 1-6).The operating frequency range that it has widened bump leveller, makes bump leveller can tackle various working condition.
Summary of the invention
The object of the present invention is to provide a kind of frequency change to respond the adjustable spring steel chip dynamic vibration absorber of fast rigidity.
The object of the present invention is achieved like this: comprise electromagnetic spring part and mass block, the bottom of described electromagnetic spring part is fixedly installed in ring-spring inside configuration, the upper end of the central shaft of electromagnetic spring part is connected with ring-spring structure, the hard-wired ring-spring structure of mass block top.
The present invention can also comprise:
1, described ring-spring structure is formed by two spring steel plate docking that bend to " U " type.
2, described ring-spring structure is double layer construction.
3, two spring steel plate docking structures that bend to " U " type are: the arranged outside of the joint of upper and lower two spring steel plates that bend to " U " type has pressing plate, between the spring steel plate of joint, liner plate is set, two-layer spring steel plate, pressing plate, liner plate are bolted and are integral.
Chief component of the present invention comprises mass block, pressing plate, liner plate, spring steel plate, electromagnetic spring, adpting flange and central shaft.Spring steel plate bends to U-shaped on request, is together fixed into ring-spring structure with pressing plate, liner plate.Mass block is threaded connection and is arranged on annular spring structure upper end, with this, forms the quality spring structure of passive type.Again electromagnetic spring is placed in to annular spring structure, forms the reliable integrated morphology of a kind of structural stability.
Mass block, spring steel plate, pressing plate etc. form the spring steel chip bump leveller of passive type.The present invention, on the basis of original electromagnetic spring, by the annular spring structure that adds spring steel plate etc. to form, has overcome the shortcoming that conventional helical formula spring is subject to the impact of installation pretightening force in engineering-environment.
Spring steel plate bends to U-shaped on request, the annular spring structure of fixing composition together with pressing plate, liner plate, and mass block is installed on annular spring structure upper end.
Electromagnetic spring partial fixing is in annular spring structure, and top is connected with adpting flange by the central shaft of drawing, and flange is fixed on annular spring structure top again.Bottom joins by screw and annular spring structure bottom.
Advantage of the present invention is to using that annular spring structure is as total supporting way, overcome the shortcoming that conventional helical formula spring is subject to the impact of installation pretightening force, make the natural frequency of bump leveller can not occur because of the difference of frock changing, and increase Area of bearing, also make center of gravity reduce, be conducive to improve the installation stability of bump leveller.Annular spring structure has good linearity simultaneously, and its rigidity can keep constant in a larger excursion.The present invention, by adding electromagnetic spring structure, has advantages of that frequency change responds fast, only needs to change electric current and can change rigidity, can on-line continuous regulate, realize and follow the tracks of the frequency changing, to adapt to the working conditions change of machinery, more can meet the absorbing requirement under different conditions.
