Currently, major main engine plants increasingly pay attention to the performance of whipping of seat, in order to pursue vehicle reach 5 star of C-NCAP and 5 stars+, have
Necessity obtains high score on whipping performance.
The major measure that current promotion seat whips experimental performance has:
1) reinforce backrest frame strength, reduce backrest dynamic subtended angle；
2) increase the height of backrest push pipe；
3) backrest push pipe is increased at a distance from human body, increases buffer distance；
4) increase the height on head pillow frame top；
5) reinforce seat headrest framework intensity, including increase the head pillow frame strength of materials, increase head pillow frame diameter, reinforce
The weld strength etc. of headrest conduit；
6) increase head pillow frame and head is bonded length；
7) top that head pillow frame is bonded with head turns forward；
8) active safety pillow is used, headrest pops up forward supporting head part when rear-end impact occurs；
9) reduce the distance of headrest to human body head；
10) reduce the distance of headrest front surface to head pillow frame；
11) increase the hardness of headrest foaming.
The above measure has following insufficient:
Above-mentioned 1st article to the 7th article measure has the drawback that: needing to change the existing structure of chair framework.Each main seat
The universal hardware and software platform of the skeleton of chair supplier, has completed a large amount of regulation and safety feature test, if change seat bone
Frame body construction, it may be necessary to re-start a large amount of performance test and verifying, seat system investment cost is higher, automobile research

In the specific embodiment of the invention, the dynamic process for whipping test using apparatus of the present invention progress C-NCAP is as follows:
Crash dummy head moves backward under the action of inertia, relative to seat, is divided into four-stage:
First stage, as shown in figure 11, crash dummy head accelerates to move to backward to be contacted with headrest foaming web surface,
During this, it is displaced S=25mm, buffers acceleration=0, acceleration aH=coaster acceleration aB≤5g is sheared on head；
Second stage, as shown in figure 12, crash dummy head from headrest foaming web surface contact accelerate to head
The contact of energy-absorption box surface is rested the head on, during this, is displaced S=20mm, headrest foamed damping acceleration ≈ 0 is (due to softer, head of foaming
Contact area is smaller), head shears acceleration aH=coaster acceleration aB- and buffers acceleration aF≤5g；
Phase III, as shown in figure 13, crash dummy head burst from accelerated motion to energy-absorption box is contacted with energy-absorption box surface
Contracting starts to collide with head pillow frame, during this, is displaced S=40mm, and energy-absorption box buffers acceleration 5g to 10g, head shearing plus
Speed aH=coaster acceleration aB- buffers acceleration aF≤5g；
Fourth stage, as shown in figure 14, crash dummy head impact head pillow frame, backrest overall deformation are buffered to head phase
0 is reduced to for seat speed, at this moment head is maximum relative to seat rearward displacement, during this, is displaced S=80mm, seat
Skeleton buffers acceleration ≈ 20g, and it is negative value that acceleration aH=coaster acceleration aB- buffering acceleration aF is sheared on head, meet≤
The requirement of 5g.
Crash dummy back moves backward under effect of inertia, relative to seat, corresponding with head movement, is also classified into four
A stage:
First stage, as shown in figure 15, crash dummy back upper end swing back to backrest upper end foam web surface
Contact, during this, average displacement S=25mm (back top moves 50mm backward, and shoulder is by back rest supports shift invariant) delays
Acceleration ≈ 0 is rushed, acceleration aH=coaster acceleration aB≤5g is sheared on head；
Second stage, as shown in figure 16, crash dummy back contact acceleration from backrest upper end foaming web surface
It moves to and is contacted with back energy-absorption box surface, during this, be displaced S=30mm, headrest foamed damping acceleration ≈ 1g to 2g (hair
Bubble is softer, but back contact area is larger), head shears acceleration aH=coaster acceleration aB- and buffers acceleration aF≤5g；
Phase III, as shown in figure 17, crash dummy back burst from accelerated motion to energy-absorption box is contacted with energy-absorption box surface
Contracting starts to collide with backrest frames, during this, is displaced buffering acceleration 5g to the 10g (ratio of S=40mm, energy-absorption box and foaming
Resting the head on, energy-absorption box buffering acceleration is smaller, and action time needs to synchronize), it is slow that acceleration aH=coaster acceleration aB- is sheared on head
Rush acceleration aF≤5g；
Fourth stage, crash dummy rushed back hit backrest frames, and backrest frames overall deformation is buffered to speed and is reduced to 0, this
When back rearward displacement it is maximum, during this, displacement S=50-60mm (to 5.7 °, whip for backrest dynamic subtended angle=4.8 ° by satisfaction
The requirement of≤10.2 ° of test), chair framework buffers acceleration ≈ 20g, and it is slow that acceleration aH=coaster acceleration aB- is sheared on head
Rushing acceleration aF is negative value, satisfaction≤5g requirement.
Although the embodiments of the present invention has been shown and described above, it is to be understood that above-described embodiment is example
Property, it is not considered as limiting the invention, those skilled in the art within the scope of the invention can be to above-mentioned
Embodiment is changed, modifies, replacement and variant.
