Description
Technical field
Technical field of automobile parts is the utility model is related to, more particularly to a kind of vehicle bump leveller.
Background technology
In vehicle travel process, vibration is that inevitable, harmful vibration can make people produce sticky feeling, and can
Cause the component structural premature breakdown for vibrating position, reduce its service life, the body of serious even entail dangers to people is good for
Health and personal safety.Therefore, technical staff is directed to research how nuisance vibration to be reduced or eliminated as far as possible always.
At present, be reduced or eliminated method for oscillating have it is a variety of, such as：Eliminate or weaken vibration source, isolation or decay vibration transmit,
Dynamic absorber, increase damping, adjustment structure etc..Wherein, dynamic absorber belongs to passive vibration damping, and more economical, effective method,
It is widely adopted in industries such as automobile, engineering machinery, machinery, building, steamer, aviations.
The general principle of dynamic absorber is：A kind of intrinsic frequency and rumble spectrum phase are added at vibrating body amplitude maximum position
The rubber dynamic vibration absorber of matching, using resonance when exciting force offseted with inertia force reaction, and rubber vibration deform and
Frictional heat decays vibrational energy in generation, and vibration noise purpose is reduced to reach.
Existing dynamic vibration absorber is mostly that mass inertia block adds absorber rubber to add the structure of mounting bracket, and product is manufacturing
Fixed into rear rubber structure and rigidity immutable.By intrinsic frequency theoretical formula：(wherein, f is intrinsic frequency
Rate, k is rubber stiffness, m is mass inertia block quality) understand, intrinsic frequency is relevant with quality and rigidity, due to empty by assembling
Between, the condition limitation such as service life and vibrating body gross mass, mass inertia block quality immobilizes unadjustable.Inhaled according to power
Shake principle, when bump leveller intrinsic frequency and excited frequency are same or like, bump leveller flourishing could vibrate to optimal reduction
Noise function, this requires the rigidity of absorber rubber to control the effect that competence exertion is best available in less scope.
