Then, the effect to above-mentioned collision test device describes.At this, Fig. 3 is the key diagram of the effect of expression collision test device shown in Figure 1, (A) the preceding state of expression collision, the state when (B) representing collision, (C) state after the expression collision, the state when (D) representing recovery.
Shown in Fig. 3 (A), the reduction gear 3 before being about to begin for impact test, axial region 32 are configured in the position of upstream, and the pressing component 37b of recovery device 37 becomes the state of keeping out of the way not with axial region 32 position contacting.In addition, the collision of clamping device 34 pilot study bodies 1 and standby under the state that specified load is put on axial region 32.Under this state, make drive unit 2 action and test body 1 is advanced on guide rail R.After becoming fixing speed drive unit 2 is stopped, utilizing inertial force to make of impact damper portion 31 collisions of test body 1 with fixing speed and reduction gear 3.
Shown in Fig. 3 (B), when test body 1 collided with the impact damper portion 31 of reduction gear 3, impact damper portion 31 was to be compressed distortion and to relax the mode effect of impacting.In addition, on axial region 32, constitute by clamping device 34 and effluxion and as one man apply specified load, utilize described load with axial region 32 brakings, test body 1 slows down with specified waveform.
Shown in Fig. 3 (C), after the collision, axial region 32 only is pressed into certain distance and stops, and test body 1 stops in the position that the repulsion that is cushioned device portion 31 thruster is upstream returned.At this moment, preferably in the temporary transient braking that finishes axial region 32 of the stage that the deceleration of testing body 1 roughly finishes, that is, preferably the brake pad 34a with clamping device 34 temporarily separates from axial region 32.By described operation, can alleviate the load that when test body 1 is stopped, producing to collision test device.And, from the stage that impact damper portion 31 separates, push brake pad 34a and axial region 32 stopped to axial region 32 once more at test body 1.Thereafter, drive unit 2 actions by making upstream side can make test body 1 side shifting and turn back to initial position upstream.
Shown in Fig. 3 (D), when making reduction gear 3 turn back to original state, make recovery device 37 action and make the rear end butt of pressing component 37b and axial region 32, axial region 32 is forwards given as security to go into to get final product., by make pressing component 37b keep out of the way, can turn back to the original state shown in Fig. 3 (A) (state before impact test begins) thereafter.
As mentioned above, first embodiment of the collision test device of the application of the invention, can easily implement collision test method, this collision test method makes mounting that simulation occupant's dummy's 11 test body 1 and reduction gear 3 collisions be arranged, thereby observation dummy's 11 situation, load, it is characterized in that, reduction gear 3 has with the impact damper portion 31 of testing body 1 collision and at front end and has the axial region 32 that impact damper portion 31 also extends along the direct of travel of testing body 1, apply and test the load of direction of the direct of travel approximate vertical of body 1 to the outside surface of axial region 32, thereby test body 1 is slowed down.
In addition, according to above-mentioned collision test device and collision test method, apply and test the load of direction of the direct of travel approximate vertical of body 1 to reduction gear 3, thus the control imposed load, can easily control the retarded velocity of test body 1 thus, the reproduction that can easily collide.In addition, the impact when bearing collision by impact damper portion 31 and clamping device 34, even therefore impact damper portion 31 is used resin molded part, the deterioration of impact damper portion 31 is also less, and the collision test device that can stand to use repeatedly can be provided.In addition, control the retarded velocity of test body 1 by the control of clamping device 34, so do not need to make accurately impact damper portion 31, can reduce the making man-hour of impact damper portion 31, can reduce the number of times of the impact test of the reproduction that is used to collide.
Then, the Waveform Control of retarded velocity to test body 1 describes.Herein, the figure of the Waveform Control when Fig. 4 is expression reproduction JIS setting, (A) expression voltage is set, (B) the expression test findings.In Fig. 4 (A), transverse axis express time (msec), longitudinal axis presentation directives voltage (V), in Fig. 4 (B), transverse axis express time (msec), the longitudinal axis is represented retarded velocity (m/s 2).

The figure of the Waveform Control when Fig. 6 represents to reproduce the collision that weighs than the JIS setting, (A) expression voltage is set, (B) the expression test findings.In Fig. 6 (A), transverse axis express time (msec), longitudinal axis presentation directives voltage (V), in Fig. 6 (B), transverse axis express time (msec), the longitudinal axis is represented retarded velocity (m/s 2).
Described collision status is to reproduce acceleration, load ratio JIS that dummy 11 is produced to set big situation.Under this situation, shown in Fig. 5 (B), retarded velocity welcomes peak value in the stage relatively early, slowly descends thereafter.In order to obtain described test findings, the command voltage of clamping device 34 is set at and keeps form roughly the same when reproducing JIS and set and the maximal value of command voltage becomes big shown in Fig. 6 (A).
In addition, the figure of the Waveform Control when Fig. 7 is expression reproduction EC restriction, (A) expression voltage is set, (B) the expression test findings.In Fig. 7 (A), transverse axis express time (msec), longitudinal axis presentation directives voltage (V), in Fig. 7 (B), transverse axis express time (msec), the longitudinal axis is represented retarded velocity (m/s 2).
Fig. 7 (B) illustrates ECER16 (Economic Commission for Europe's the 16th rule), and different with the condition of JIS in this rule, the rising of retarded velocity is very fast, and retarded velocity is also set greatlyyer, and the retarded velocity convergent time is also set shortlyer.And, converge on the mode in the allowed band of shade among Fig. 7 (B) with test findings, shown in Fig. 7 (A), carry out voltage and set.The command voltage of clamping device 34 for example rises at about 20msec, gets maximal value at about 50msec, at about 70msec command voltage is sharply descended.Set by this voltage, can obtain the test findings shown in Fig. 7 (B).
The content of above-mentioned Fig. 4~Fig. 7 is an example of the Waveform Control of retarded velocity, is not limited thereto, and can set various command voltages according to the retarded velocity of asking for.Therefore, according to collision test device of the present invention and collision test method, can carry out the Waveform Control of retarded velocity with the command voltage of clamping device 34, therefore obtain and easily to carry out excellent results such as voltage is set, the accumulation of data is easy, simulation is easy, the reproduction that can easily collide.In addition, carry out different voltage settings, also can carry out thinner control by clamping device 34 or individual other clamping device 34 for the front and back section.
At last, other the embodiment for collision test device of the present invention describes.At this, Fig. 8 is the figure of other embodiments of expression collision test device of the present invention, (A) is second embodiment, (B) is the 3rd embodiment, (C) is the 4th embodiment.To the component parts mark same numeral identical with above-mentioned first embodiment, the repetitive description thereof will be omitted.
