Then, the effect of above-mentioned collision test device is described.At this, Fig. 3 is the key diagram of the effect representing the collision test device shown in Fig. 1, and (A) represents the state before collision, and (B) represents state during collision, (C) represent the state of collision rift, (D) represents state when recovering.
As shown in Fig. 3 (A), be about to the reduction gear 3 before starting for impact test, axle portion 32 is configured in the position of most upstream, and the pressing component 37b of recovery device 37 becomes the state of keeping out of the way the position do not contacted with axle portion 32.In addition, the collision of clamping device 34 pilot study body 1 and standby under the state that specified load is put on axle portion 32.Under this state, make drive unit 2 action and test body 1 is advanced on guide rail R.Make drive unit 2 stop after becoming fixing speed, utilize inertial force that test body 1 is collided with the impact damper portion 31 of fixing speed and reduction gear 3.
As shown in Fig. 3 (B), when test body 1 is collided with the impact damper portion 31 of reduction gear 3, impact damper portion 31 is also to be relaxed the mode effect impacted by compression deformation.In addition, in axle portion 32, to be configured to by clamping device 34 with the time through as one man applying specified load, utilize described load to be braked in axle portion 32, test body 1 is slowed down with specified waveform.
As shown in Fig. 3 (C), collision rift, axle portion 32 is only pressed into certain distance and stops, and test body 1 stops in the position that the repulsion upstream thruster being buffered device portion 31 is returned.Now, preferably temporarily terminate the braking in axle portion 32 in the stage that the deceleration of test body 1 roughly terminates, that is, preferably the brake pad 34a of clamping device 34 is temporarily separated from axle portion 32.By described operation, the load to collision test device produced when making test body 1 stop can being alleviated.Further, in the stage that test body 1 is separated from impact damper portion 31, again press brake pad 34a to axle portion 32 and axle portion 32 is stopped.Thereafter, by making drive unit 2 action of upstream side, test body 1 can be made upstream to move and turn back to initial position in side.
As shown in Fig. 3 (D), when making reduction gear 3 turn back to original state, make recovery device 37 action and pressing component 37b abutted with the rear end in axle portion 32, axle portion 32 is forwards given as security into.Thereafter, by making pressing component 37b keep out of the way, original state shown in Fig. 3 (A) (impact test start before state) can be turned back to.
As mentioned above, first embodiment of the collision test device of the application of the invention, easily can implement collision test method, this collision test method makes the test body 1 of the dummy 11 being placed with simulating crew collide with reduction gear 3, thus the situation of observation dummy 11, load, it is characterized in that, reduction gear 3 has the impact damper portion 31 of colliding with test body 1 and has impact damper portion 31 in front end and the axle portion 32 extended along the direct of travel of test body 1, outside surface to axle portion 32 applies the load in the direction substantially vertical with the direct of travel of test body 1, thus test body 1 is slowed down.
In addition, according to above-mentioned collision test device and collision test method, apply the load in the direction substantially vertical with the direct of travel of test body 1 to reduction gear 3, thus control imposed load, thus can the retarded velocity of easily Control experiment body 1, easily can carry out the reproduction of colliding.In addition, impact when bearing collision by impact damper portion 31 and clamping device 34, even if therefore use resin molded part to impact damper portion 31, the deterioration in impact damper portion 31 is also less, can provide the collision test device that can stand Reusability.In addition, carried out the retarded velocity of Control experiment body 1 by the control of clamping device 34, therefore do not need to make impact damper portion 31 accurately, the making man-hour in impact damper portion 31 can be reduced, the number of times of the impact test for the reproduction of colliding can be reduced.
Then, the Waveform Control of the retarded velocity of test body 1 is described.Herein, Fig. 4 is the figure of the Waveform Control represented when reproducing JIS setting, and (A) represents voltage sets, and (B) represents test findings.In Fig. 4 (A), horizontal axis representing time (msec), longitudinal axis presentation directives voltage (V), in Fig. 4 (B), horizontal axis representing time (msec), the longitudinal axis represents retarded velocity (m/s
2).
In Fig. 4 (B), shadow region represents the allowed band of the retarded velocity of the chassis of the dynamic loading experiment recorded in JISD4604.That is, when carrying out impact test under the condition recorded in JISD4604, the retarded velocity of test body 1 must be made to be in this allowed band.
In order to meet described condition, as shown in Fig. 4 (A), control servo-valve 34c.To about 50msec, such as periodically make command voltage increase, only after the certain hour of tens of msec degree maintains peak value, till making command voltage drop to about 100msec degree lentamente, only during about 20msec, command voltage is reversed, thereafter, command voltage is made to remain certain.Like this, by the command voltage of the clamping device 34 shown in control chart 1 and Fig. 2, the test findings shown in Fig. 4 (B) can be obtained.This means, by controlling the command voltage of clamping device 34, the load change applied to axle portion 32 can be made, the Waveform Control of the retarded velocity of test body 1 can be carried out.
In addition, as shown in Fig. 5 ~ Fig. 7, in collision test device of the present invention, various collision can be reproduced by changing voltage sets.At this, Fig. 5 is the figure representing the Waveform Control reproduced when setting light collision than JIS, and (A) represents voltage sets, and (B) represents test findings.
In Fig. 5 (A), horizontal axis representing time (msec), longitudinal axis presentation directives voltage (V),
In Fig. 5 (B), horizontal axis representing time (msec), the longitudinal axis represents retarded velocity (m/s
2).
When described collision is reproduced, as shown in Fig. 5 (A), control servo-valve 34c.Such as, with rise to maximal value at about 20msec about about 50%, the mode that becomes maximal value at about 50msec makes command voltage slowly rise, to about 90msec, command voltage is made to be roughly necessarily or after slightly subtracting, command voltage is slowly declined, after only making command voltage reverse during about 20msec, command voltage is remained certain.Like this, control the command voltage of clamping device 34, thus as shown in Fig. 5 (B), although the numerical value of retarded velocity is little, the light collision status that the long time produces roughly certain retarded velocity can be reproduced in.
Fig. 6 represents the figure of Waveform Control when reproducing the collision heavier than JIS setting, and (A) represents voltage sets, and (B) represents test findings.In Fig. 6 (A), horizontal axis representing time (msec), longitudinal axis presentation directives voltage (V), in Fig. 6 (B), horizontal axis representing time (msec), the longitudinal axis represents retarded velocity (m/s
2).
Described collision status is that acceleration, the load ratio JIS reproduced dummy 11 produces sets large situation.In this situation, as shown in Fig. 5 (B), retarded velocity welcomes peak value in the stage relatively early, slowly declines thereafter.In order to obtain described test findings, the command voltage of clamping device 34, as shown in Fig. 6 (A), is set as maintaining roughly the same form when setting with reproduction JIS and the maximal value of command voltage becomes large.
In addition, Fig. 7 is the figure of the Waveform Control represented when reproducing EC restriction, and (A) represents voltage sets, and (B) represents test findings.In Fig. 7 (A), horizontal axis representing time (msec), longitudinal axis presentation directives voltage (V), in Fig. 7 (B), horizontal axis representing time (msec), the longitudinal axis represents retarded velocity (m/s
2).
Fig. 7 (B) illustrates ECER16 (Economic Commission for Europe the 16th rule), and in this rule, different from the condition of JIS, the rising of retarded velocity is very fast, and retarded velocity also sets larger, and the time of retarded velocity convergence also sets shorter.Further, converge on the mode in the allowed band of shade in Fig. 7 (B) with test findings, as shown in Fig. 7 (A), carry out voltage sets.The command voltage of clamping device 34 such as rises at about 20msec, gets maximal value, at about 70msec, command voltage is sharply declined at about 50msec.By this voltage sets, the test findings shown in Fig. 7 (B) can be obtained.
The content of above-mentioned Fig. 4 ~ Fig. 7 is an example of the Waveform Control of retarded velocity, is not limited thereto, can sets various command voltage according to the retarded velocity asked for.Therefore, according to collision test device of the present invention and collision test method, the Waveform Control of retarded velocity can be carried out with the command voltage of clamping device 34, therefore obtain can easily carry out voltage sets, data accumulation easily, simulate the excellent results such as easy, easily can carry out the reproduction of colliding.In addition, by carrying out different voltage sets for the clamping device 34 of front and back section or other clamping device 34 individual, also thinner control can be carried out.
Finally, other the embodiment for collision test device of the present invention is described.At this, Fig. 8 is the figure of other embodiments representing collision test device of the present invention, and (A) is the second embodiment, and (B) is the 3rd embodiment, and (C) is the 4th embodiment.Mark identical label to the component parts identical with above-mentioned first embodiment, the repetitive description thereof will be omitted.
The second embodiment shown in Fig. 8 (A) is following embodiment: the clamping device 34 of leading portion and back segment each in, the hydraulic cylinder that the hydraulic cylinder 34b of volume ratio rank rear is little is adopted to the hydraulic cylinder 34b ' in prostatitis.Like this, between the hydraulic cylinder 34b ' and the hydraulic cylinder 34b of rank rear in prostatitis, give change to cylinder capacity, complicated or trickle load can be realized thus and control.
The 3rd embodiment shown in Fig. 8 (B) only configures one group of clamping device 34.One group refers to the combination of the clamping device 34 with four hydraulic cylinder 34b and servo-valve 34c at this, but is not limited thereto.In addition, in the third embodiment, the Ellipsis recovering device 37 because axle portion 32 length is shorter.Therefore, in said embodiment, when axle portion 32 recovers, axle portion 32 is manually forwards pressed into by operator.The combined arrangement of the group number of clamping device 34 and one group suitably changes according to conditions such as the capacity of hydraulic cylinder 34b, the weight of test body 1 and speed, necessary load or retarded velocity.
The 4th embodiment shown in Fig. 8 (C) is the embodiment symmetrically configured in the both sides of main part 33 by hydraulic cylinder 34b.That is, hydraulic cylinder 34b is relative to the peripheral direction in axle portion 32, when setting top as 0 °, symmetrically configures in the position of 90 ° and 270 °.In addition, when axle portion 32 is quadrangular shape illustrated with dotted line, the outside surface being configured to axle portion 32 configures along the direction parallel with ground G with direction vertical with it.Even if in said embodiment, also play the effect same with the first embodiment.
