In another embodiment, the connecting rod 130 is made of Elastic Carbon fibrous material.Carbon fiber is a kind of high-strength
The new fiber materials of degree, high modulus fibre, light weight, intensity are high, the not only intrinsic intrinsic property with carbon material, and simultaneous
The soft machinability of standby textile fabric.The connecting rod 130 of setting carbon fibre material can play simulation human body in housing 110
The effect of bone.
Exportable formula elastic mechanism be set in same cavity 111 up and down between two connecting plates 120 and with upper and lower two
Connecting plate 120 is fixedly connected, the quantity of the quantity of the exportable formula elastic mechanism and connecting rod 130 in same cavity 111
It is identical.Output line is provided on the exportable formula elastic mechanism, the output line is pierced by through cable hole 112.Exportable formula bullet
Property mechanism can provide elastic anchorage force, and the size of power is exported, while by the size of power output obtain it is described can be defeated
Go out the deformation quantity of formula elastic mechanism.
In another embodiment, 110 top of housing is provided with head connecting hole, described for connecting manikin head
Housing bottom is provided with chest connecting hole, for connecting dummy breast.
By above-mentioned arrangement, dummy used in car crash experiment neck replacement device provided by the invention can be applied to automobile
On crash test dummy, the neck of conventional dummy, and head connecting hole and housing by being set to 110 top of housing are replaced
Device provided by the invention is installed between head and the chest of conventional dummy by the chest connecting hole of bottom.The present invention can play
The effect of neck is simulated, while the stress of each measurement point of neck can be accurately measured using exportable formula elastic mechanism
Situation and deformation situation provide accurate data for vehicle impact testing and support.
As shown in figure 4, being embodiment another, the exportable formula elastic mechanism includes air spring 141, gas-guide tube
142 and pressure gauge 143.
The air spring 141 be set in same cavity 111 up and down between two connecting plates 120 and with upper and lower two companies
Fishplate bar 120 is fixedly connected.Air spring 141 is to enter gas in closed cavity, is more than the pressure in air spring 141 big
Atmospheric pressure, using the compressibility of gas, the gas when air spring 141 is compressed in it can also compress.Since collision tries
It is very short to test the time collided in the process, regards collision process approximation as adiabatic process, according to the equation of gas state, in adiabatic compression
Under the conditions of, the pressure rise of gas, and then the reverse elasticity power that air spring 141 provides increases, and air spring 141 therewith
Elastic force and be non-linear relation between decrement.
In collision process, 141 pairs of air spring and two connecting plates 120 that it connect play resilient support and buffering
Effect.The support to neck bone such as muscle, soft tissue can be preferably simulated using air spring 141.In the present embodiment,
Setting is there are four air spring 141 in each cavity 111, i.e., the quantity of air spring 141 and connection in same cavity
The quantity of bar is identical, and air spring 141 is located at connecting rod 130 on same circumference, and is uniformly distributed in interval, the circumference
Centered on the axis of housing 110.
Pressure gauge 143 is provided with outside housing 110, the pressure gauge 143 is connected by gas-guide tube 142 and air spring 141
It connects.Gas-guide tube 142 is pierced by by cable hole 112 to outside housing out of described housing 110.Each air spring 141 passes through one
A individual gas-guide tube 142 is connect with an individual pressure gauge 143.Gas in air spring 141 is measured using pressure gauge 143
Pressure, the stress size of air spring 141 can be obtained, and be obtained simultaneously air spring 141 by decrement.
Neck replacement device provided by the invention is used to simulate the neck joint muscle and soft tissue of people, wherein air bullet
For simulating muscle and soft tissue between two joints, the load condition of the air spring 141 can correctly reflect spring 141
Go out the load of neck, measurement data has stronger reliability.Obtained pressure value is measured by pressure gauge 143, it can be straight
It connects to obtain the compressed load of air spring 141.Such as pressure gauge 143 measures in same cavity 111 four air springs 141
Pressure value is respectively P1、P2、P3、P4, this four 141 initial pressure values of air spring are P0, in this four air springs 141
For first, the compressing force being subject to is F1=P1S, S are the cross-sectional area of air spring 141.Through the above way directly
The stressing conditions between two joint are obtained.
In addition to neck joint stress is crossed other than conference causes neck injury to passenger in collision process, neck joint
Between relative displacement is excessive that equally neck can be caused to damage.Therefore measuring the relative displacement between neck joint equally has extremely
Close important meaning.
It is located at the decrement of four air springs 141 in same cavity 111 by measurement, adjacent two can be obtained indirectly
The variation of angle between a joint.Can be approximately adiabatic process by collision process since collision time is relatively short, therefore
Meet
Wherein V0For air spring initial volume, V1、V2、V3、V4Respectively four air springs are by compressed volume, κ
For adiabatic coefficent, a is constant and experiment method can obtain simultaneously.
The amount that first air spring 141 is compressed is
In above formula, P1It is measured by pressure gauge, other parameter is known parameters, therefore can directly obtain first air
The amount L that spring 141 is compressed1.It similarly can obtain the amount L that other three air springs 141 are compressed2、L3、L4。
After four air springs 141 are compressed, because respectively making two joints generation angle up and down by decrement difference
Degree, the joint of neck equally produces larger angle, meeting if the angle is excessive it is believed that during actual collision
Neck is caused to damage.
Uniformly distributed four air springs 141 in same cavity 111 in the present embodiment, this four air springs 141 are with housing
It is circularly and evenly distributed centered on 110 axis, the distance between two neighboring air spring 141 is b.Due to 3 points of compositions one
A plane, therefore only need to calculate the amount L that three air springs 141 are compressed1、L2、L3, you can the cavity is obtained two about 111
Angle theta between a connecting plate 120
M=2b (L1-L3)
N=2b (L1-L2)
R=-4b2。
Angle of the cavity about 111 between two connecting plates 120 is acquired by above formula, is done between your neck joint
Angle, the bending degree for neck joint in collision process provide data support.
Although the embodiments of the present invention have been disclosed as above, but its be not restricted in specification and embodiment it is listed
With it can be fully applied to various fields suitable for the present invention, for those skilled in the art, can be easily
Realize other modification, therefore without departing from the general concept defined in the claims and the equivalent scope, it is of the invention and unlimited
In specific details and legend shown and described herein.
