Description
Technical field
The invention belongs to vehicle resin panel field shaping techniques, are specifically related to a kind of noise reduction resin face for vehicle
The forming method of plate.
Background technology
Noise is various to Health Impact, and function of noise makes the brain of people in the central nervous system of people
Cortex excitement and inhibition dysequilibrium, cause conditioned reflex abnormal, cerebrovascular tension are made to be damaged, it may appear that dizzy, headache,
The symptoms such as insomnia, failure of memory, severe patient can generate amentia, lead to agitation, insomnia, neurasthenia, short-tempered etc.
Problem makes one slow in reacting, and working efficiency reduces, and takes sb's mind off sth, causes operating irregularity.The intensity of noise is bigger, and frequency is cured
High, action time, longer, personal endurance was smaller, then endangered more serious.Statistics shows that 80dB (A) noise below will not
Cause noise deafness；The noise of 80dB (A)~85dB (A) can cause slight hearing impairment；85dB (A)~100dB's (A)
Noise can cause a certain number of noise deafness；And when more than 100dB (A), fairly large number of noise ear can be caused
It is deaf.For people in the case of no mental preparation, high the knocking property noise of intensity can make hearing exist (as blown out explosion time suddenly)
Permanent loss in a flash generates knocking property deafness, at this moment, the hearing organ of people will suffer from severe trauma, seriously affect people
Working and learning, therefore, control and eliminate Noise upon Environment pollution and to people life, work harassing and wrecking seem especially heavy
It wants.
In recent years, urban motor vehicle increases quickly, and incident traffic noise pollution environmental phenomenon also becomes increasingly conspicuous.
Automobile brings modern material progress to the world, but also brings the social concerns such as pollution from environmental noise simultaneously.Expert thinks, vapour
One of vehicle harm maximum to environmental protection is noise pollution.Actually, what the most noisy noise in city ranked first should belong to car horn
Sound.It walks on road, what seething automobile belt came is a burst of ear-piercing tucket, and no matter you are in office, classroom, doctor
Institute, family, tucket all cannot equally allow your ear quiet, and car noise not only increases the fatigue of driver and occupant, and
And influence the driving safety of automobile.As the important evaluation index of vehicle ride comfort, car noise also can be largely
On reflect the design level and technological level of manufacturer.Therefore, control car noise to floor level be also Automobile Design
The direction that person pursues.
The approach of existing auto sound is mainly the following：
From the noise control measure of theory of mechanics：
It improves mechanical equipment structure, carry out noise reduction using new material：With the development of material science and technology, various new materials are met the tendency of
And give birth to, come true with rub in some larger, high damping alloy, highstrenghtpiston's production machine parts.Such as in vapour
Just through frequently with highstrenghtpiston's parts in vehicle production.
Improve parts machining precision and assembling quality：The raising of parts machining precision makes to rub between parts to subtract as possible
It is few, to make lower noise；Assembling quality is improved, eccentric vibrating is reduced, and improve the rigidity etc. of casing, machine can be made to set
Standby noise reduces.
From the noise control measure of Principles of Acoustics：Include mainly sound-absorbing, sound insulation, damping, sealing etc..
It is well known that the important component of composition vehicle is exactly body panels, therefore, body panels not only want by apparent weight,
Mechanical performance and anti-acoustic capability are more important.Traditional body panels can be made of sheet metal, be wanted as sheet metal
Reach the satisfactory rigidity of body panels and intensity, it is necessary to increase the thickness of steel plate, or by a large amount of supporting beam come
Support the car body panel of sheet metal, so that the production cycle of entire body panels plank is long, and cost increases, and overall weight carries
Height increases energy consumption, and anti-acoustic capability is poor, and some body panels mostly use vibration damper plate and sound-absorbing pad to reach Noise Reduction
Deng the soundproof effect of this panel is poor, and mechanical strength is inadequate, therefore, how to obtain a kind of mechanical strength and noise reduction all
Preferable body panels are current automobile industry urgent problems to be solved.
