Abstract
The invention discloses a method for changing natural frequency of a damper. The method of the present invention is realized by the following technical scheme that: under the constant product structure condition, on the premise of stabilization of the sulfurization process, the natural frequency of the damper has a direct relationship with elastic modulus of a rubber material, after the use amounts of other components in the damper material formula are fixed, improvement of the use amount of carbon black is the method for directly improving the natural frequency, wherein the improvement of the use amount of carbon black is that: the use amount of the carbon black with the mass ratio of 4-8% is increased. Compared to the prior art, with the present invention, the simple and feasible method for changing the natural frequency of the damper is provided.
Description
Technical field
The present invention relates to the automobile component field, more particularly, relate to a kind of method that changes the deoscillator natural frequency.
Background technology
The natural frequency difference that the deoscillator that the automobile of different model uses needs, the natural frequency that the deoscillator that same automobile different sites uses needs is also different, to not reporting in the inflation method prior art of deoscillator natural frequency.
Summary of the invention
Technical problem to be solved by this invention is, overcomes the deficiency that exists in the prior art, and a kind of method that changes the deoscillator natural frequency is provided.
The present invention changes the method for deoscillator natural frequency; Be achieved through following technical proposals, under the constant condition of product structure, stablizing under the prerequisite of sulfuration process; The natural frequency of deoscillator and the Young's modulus of sizing material have direct relation; Behind the consumption of other components, improving carbon black loading is the method that directly improves natural frequency in fixedly damper material is filled a prescription, and said raising carbon black loading is meant the carbon black loading that increases mass ratio 4%-8%.
Said raising carbon black loading is the consumption that improves the kind of carbon black that particle diameter is big relatively in the damper material prescription.
The relative prior art of the present invention provides a kind of method of simple change deoscillator natural frequency.
Embodiment
In the face of doing, the present invention further describes down.
Change the Young's modulus of vulcanized rubber through change prescription infill system and grease amount, and then change the natural frequency performance of deoscillator, concrete experimental result is seen table 1 as follows.
In experimentation, we find: stablizing under the prerequisite of sulfuration process, the frequency of deoscillator and the Young's modulus of sizing material have direct relation.After fixing other cooperated consumption, improving carbon black loading was the method that directly and effectively improves frequency.Can find from 1348-1 and 1348-3 experimental result, improve 8 parts of N774 consumptions, frequency improves 5 values.But kind of carbon black is different to the influence of frequency, and particle diameter is big more, just says that also hard(carbon)black is bigger to the influence of frequency than soft carbon.Can find that from the experimental result of 1348-1 and 1348-2 the umber that improves N550 can significantly improve frequency numerical value.
We also find in the experimentation, the technology the when factor that influences frequency also comprises sulfidization molding.Curing time, curing temperature all has material impact to frequency.On the whole through improving the frequency that state of vulcanization that temperature and time improves sizing material can improve deoscillator, but after state of vulcanization reach a certain height, frequency will not stablized and can increase.
We also find in experimentation, can reduce frequency numerical value to a certain extent through increasing grease amount, but frequency just can not reduce behind the peaking.So through summing up, on the deoscillator behind the solid shape, can change the natural frequency of deoscillator through the Young's modulus that changes rubber, more direct method is through carbon black, the state of vulcanization of greasy consumption and adjusting rubber.But the change of rubber modulus has a peak value, and reaching will be very small to elastic change through above measure behind the peak value, thereby the change of frequency also can be very small.So bigger regulative mode can only be realized through changing the vibroshock structure.
Embodiment recited above describes the preferred embodiment for the present invention; Be not that design of the present invention and scope are limited; Under the prerequisite that does not break away from design philosophy of the present invention; Common engineering technical personnel make technical scheme of the present invention in this area various distortion and improvement all should belong to protection scope of the present invention.
