Car collision is a very complex big displacement, great strain is nonlinear physical process, bound variable amounts to on 1000 kinds. And when car collision happens, security reflects the passivity of the car to be out of shape in the structure that adopts bodywork just about draw collision energy, reduce the member that multiply and the rate that the pedestrian gets harm thereby. Accordingly, improving car structure to fight the important method that bumps into a gender is to pass reasonable construction and material itself to draw more collision energy, lessen the energy impact that place of personnel of collision both sides suffers thereby.
Already passed in 21 centuries so fast 20 years when, if return somebody to say " the car that the car with large board is safety " , you are completely then OK " the message that rejects him, answer his supercilious look " . Why so say? The author cites a case to everybody below.
History on the collision test of the most severe exacting accuses you are sucked can importance
If everybody still has impression, the car that this cropland two years ago once made the first whole course of domestic be made public external is right car impact test, caused the wide attention inside course of study at that time. Besides because be first whole journey fair above, this the slashing degree of collision condition also is unprecedented. To 15 degrees of car, horn when the car collision, 25% collision overlap 56km/h of rate, respective speed when a few such keywords gather, without doubt this is the collision of the most severe exacting tests the market.
Since IIHS of society of assurance of American highway safety 2012 open 25% fronts slant after buy collides, this test is peremptory the slippery iron Lu that makes numerous car brand, include Ao Di even, run quickly, Leikesasi inside model of one numerous luxurious brand also was obtained only in the test " Poor " the poorest grade, however this below Tian Qi elegant cabinet when those, thought of the model such as region, Odyssey to be obtained however " Good " highest grade.
The circumstance that checks this however different. Although was used likewise of 25% slant buy jackknife rate, but IIHS is car and fixity body barge against, speed is 64km/h; And the test of this cropland collides to the car for the car, relative speed exceeds 100km/h. And because suffer force face to all be irregular object and rather than hard wall barrier, the result of collision also cannot accuse more. In addition, 15 ° horn also can better imitate is true on road to bumping into an accident, for instance car sideslip or hit steering wheel urgently to bring about with to barge against of all along car
Cabin all does not have the multiply member that the result that collision checks is car of test of two elegant cabinet to be out of shape apparently, 4 door can be opened smoothly, the harm that no matter be the crucial position such as the head of driver's seat dummy or dummy of deputy driver's seat, bosom,gets is worth far under fiducial value, value of the greatest harm also is fiducial value only 60% the left and right sides, performance is very excellent. This means feasibility condition to if produce so serious accident,fall, the driver of two cars is OK " get off by oneself processing accident " .
No matter be the collision of IIHS,test result still is this him cropland check a result to bumping, what body comes out now is this cropland suck on design of automobile body structure can concept. This him cropland is called " ACE " full name of automobile body construction is " Advanced Compatibility Engineering " , metaphrase comes over even if bear the weight of structure of type automobile body. Among them very crucial part depends on be being used at sucking besides convention can outside frame carling, the ACE automobile body of this cropland increased top wearing and sill to be reached dispersedly draw energy, go to energy dispersedly before automobile body on pillar and floor, the component construction that avoids sill and car of the other side thereby produces amlposition, promotion collision energy absorbs efficiency, drop the negative charge of cabin of pair of the member that multiply considerably. Other model calculates there is corresponding metallic construction in this position, also not be a key prevent collision construction, design and use material not identical also.
In fact, suffer oneself of car of be confined to inherent structure, its drive security is impossible to promote indefinitely. Here the condition falls, if can consider from integral structure, of the oneself when developing car adequately to happen in collision absorb collision energy capacity, be out of shape through car collision generation namely, alleviate thereby the member that multiply and brunt be sufferringed by collision square place, it is the method of a kind of effective apparently. And " collision compatibility " concomitant and safe concept, let even if the two cars barge against with size, different weight, also won't let any one party get too big loss, this is the fundamental trend that safety of prospective car passivity develops more.
Actually the author sees this field at that time after experimenting to bumping, ever laughed at Yan Bentian " courage is not quite great still " . If not be two elegant cabinet to the model that bump, however elegant cabinet and with level some heart fastens a car, the multiply member that two cars compare after the test protects a level, not be more can interesting, more overturn the inherent acknowledge of compatriots? Of course, this just plays joke one sentence. However a fact is this cropland however tall fraction always is taken in test of collision of safety of alive bound each country. Take highest fraction one after another in Chinese C-NCAP not only, it is namely in test of collision of stricter beauty, Europe, day, this cropland also is high component frequenter. And in home, this cropland also is the car look forward to that drives automobile safety actively to travel, hold or sponsorred the propagandist promotion of a series of automobile safety.
(this cropland undertook Sai Bo 2015 farsighted with the speed per hour of Odyssey 50 kilometers front collides experiment, of collision slant buy rate is 50% . The experiment shows, ACE bears the weight of construction of type automobile body removed very good protection to bilateral car member. )
When accident happening, the person's life is in the first forever, all safety precautions ought to be to be will bilateral place to suffer harm to reduce lowest to serve. So, "Suck can " should not understand for the car too soft, "The safety for everybody " also not be him sacrifice will protect others absolutely. And result of test of so called collision is good saying is cannot reflect true condition " should try education " , the actor heterodoxy of foreign test result is homebred quality different, can be real ground only for black and black.
The car is small quantified trend decided armor plate can become thinner only
The car is small quantifying already was to cannot go against the tide that turn, because light quantify brought profit really too much. Reduce oily cost besides what everybody can think of outside, automobile body reduces the weight that still can reduce the construction that prop up again, lower automobile body inertial, promote car to quicken function and function of apply the brake thereby, more the promotion that is helpful for car security.
Passing light simple stuff to decrease is in recent years automobile industry is in again light quantify the important method that goes up to be used generally. No matter be to employ aluminium alloy, magnesium alloy, still be the material such as high strenth steel, primary purpose depends on using fewer material to achieve same better even automobile body security. Because these pledge material has better tension on unit area gently,approach function and fatigue resistance can, the material with the fewer use that changes character can have the automobile body strength that uses place of more and common armor plate to have originally.
Besides using light qualitative data, using small system structure also is also can achieve light quantified effect. Such as becomes sectional hollowly, thickening spends the advanced structure such as dimensional curved surface, Bao Bigao muscle, those who promoted automobile body member is large change the level that reachs automobile body surface, reduced the amount of automobile body structural member, promoted automobile body member bear the weight of efficiency, make material of use automobile body fewer.
It is to use light simple stuff to still design small system structure no matter, should fall to solid car to show customer at the moment when, what place expression comes out is car becomes light, board is so not large. Dot and this heart fasten a car or day department car has nothing to do, this is the tendency that whole world car develops. The B6 before believing everybody to be able to contrast 9 years strides the lengthen edition B8 that vacate and just appeared on the market this year vacate, in automobile body considerably below the premise that lengthen increases, automobile body weight differs unexpectedly very few lighter even. If say board is large,delimit with safety the word of equal-sign, does the car that is nowadays whole world then become no longer safe?
The thing that forgot armor plate, suck with automobile body can protecting the member that multiply just is correct path
In car automobile body, have delay rinse can the structure of action basically includes bumper, white automobile body, roof, door, engine cover and other interior trim etc. The data that improves these amortize compositions is formed and functional design, raise its to absorb the ability of blow energy, ability achieves the function that improves automobile safety defend, the person that effective protection car drives and the person of the member that road hands in a person of wide knowledge and sound scholarship are safe, although appear,the accident also can get harm to reduce lowest.
(this cropland undertook mixing using test of collision of edition elegant cabinet 2016, the suction that developed technology of ACE automobile body likewise as a result can advantage, the face;burst;ulcerate;festers apparently before shrink, but door can be opened normally, very effective to passenger protection. )
And these problems need a car to stylist and academic worker try to study carefully and try check ability to solve through relapsing, also be the main technique difficult problem that in developing a process, current car should try to be solved mainly. This has important academic sense to enhancing car collision security not only, also have important real sense to making sure property of life of the member that multiply is safe.
The ply that forgot armor plate so, also fasten weight of reoccupy automobile body to measure a vehicle safe.
