In the vehicle collision simulation test apparatus of Example 1, as shown in Figs. 1 and 2, the sled 15 is a frame member having a plate having a predetermined thickness, and it is a front and rear direction when viewed in plan (Fig. 1 and In Fig. 2, a long rectangle is formed in the horizontal direction). On the bottom surface 12, a pair of left and right rails 13a and 13b are provided along the front and rear direction at predetermined intervals, and the sled 15 passes through the sliders 14a and 14b fixed to the bottom surface thereof. It is supported so that forward and backward movement along 13a, 13b) is possible.
Moreover, the sled 15 can mount the specimen 16 on the upper surface. In this embodiment, the specimen 16 is a vehicle having only a skeleton, a so-called white body, in which equipment such as a seat 16a, a steering 16b, an airbag 16c, etc. is mounted, and a dummy 16d is mounted. . This specimen 16 is mounted at a predetermined position in the sled 15 and fixed by a fixture not shown.
In addition, the specimen 16 is a white body here, and includes the seat 16a, the steering 16b, the airbag 16c, and the dummy 16d, but the white body, the seat 16a, the steering 16b, and the airbag (16c) and the dummy 16d may be called a specimen as a single body in some cases.
In addition, in this embodiment, since the specimen 16 is mounted on the sled 15, the front of the vehicle which is this specimen 16 (the left direction in FIGS. 1 and 2) is the front of the sled 15. The rear of the vehicle (the right direction in FIGS. 1 and 2) serving as the specimen 16 will be described as the rear of the sled 15. In addition, the side of a vehicle which is the specimen 16, ie, the left-right direction (upper direction and lower direction in FIG. 1 and FIG. 2), is demonstrated as the lateral direction, ie the left-right direction of the sled 15. As shown in FIG.
In the vehicle collision simulation test apparatus of this embodiment, a launch device 17 as a sled acceleration device that imparts rearward acceleration to the sled 15 is provided on the bottom surface 12 on the front side of the sled 15. It is. This launch device 17 is hydraulically controlled (or air pressure control, friction control, etc.) and has a piston 17a that is projected out to the sled 15 side. Therefore, since the launching device 17 punches out the piston 17a in a state where the tip of the piston 17a is in contact with the front end of the sled 15, the impact force to the rear with respect to the sled 15 is obtained. That is, acceleration can be given. In other words, imparting the rear acceleration to the sled 15 by the launching device 17 is the same as receiving the rear acceleration when the specimen 16 on the sled 15 collides with the front face, and is simulated. It can cause a car crash.
In the front portion on the sled 15, an induction device 21 positioned in front of the specimen 16 is provided. In the instrument 21, as shown in FIGS. 3 and 4, the mounting table 22 is fixed on the sled 15, and the support shaft (B) 23 is attached to the mounting table 22 by the bracket 23. 24) is installed. This support shaft 24 is arrange | positioned along the horizontal left-right direction orthogonal to the front-back direction which is the moving direction of the sled 15. As shown in FIG.
The tow board 25 forms the plate shape by which the intermediate part was bent at the predetermined angle, and the intermediate part used as a bending part is supported by the support shaft 24 so that rotation is possible. This tow board 25 has the inclination part 25a in the front side of the sled 15, and the horizontal part 25b in the back side of the sled 15, and is horizontal with the inclination part 25a. The part 25b is connected in the intermediate part, and is integrally formed. The inclined portion 25a extends upwardly above the sled 15 from the middle portion (support shaft 24) and is set at a predetermined angle θ1 with respect to the upper surface of the sled 15. On the other hand, the horizontal portion 25b extends from the middle portion (support shaft 24) to the rear side of the sled 15 and is set substantially parallel to the upper surface of the sled 15. In this case, in the tow board 25, the inclination part 25a corresponds to the tow board which divides the engine room and the crew room, and the horizontal part 25b corresponds to the floor board which comprises the floor of the crew room.
The tow located in front of the toe board 25 in front of the toe board 25 and giving acceleration toward the rear of the inclined portion 25a on the toe board 25 and below the horizontal portion 25b. The launch device 26 as a board acceleration device is arranged. This launch device 26 is hydraulically controlled (or air pressure controlled, friction controlled, etc.) and has a piston 26a which is projected to the tow board 25 side.

That is, the launching device 26 can apply a rotational force so that the tip of the inclined portion 25a moves backward with respect to the toe board 25 and the tip of the horizontal portion 25b moves downward.
This launch device 26 simultaneously operates when imparting rear acceleration to the sled 15 by the launch device 17 to impart rear acceleration to the tow board 25. That is, when the acceleration is applied to the sled 15 by the launching device 17 and the back acceleration is received when the specimen 16 on the sled 15 collides with the front face, the towing is carried out by the launching device 26. By applying the acceleration to the board 25, the tow board 25 on the sled 15 is shaped to receive the rear acceleration (deformation) due to the front collision, which can simulate the automobile crash. .
Here, the operation of the vehicle collision simulation test apparatus of the first embodiment will be described.
When the vehicle collision test is performed by the vehicle collision simulation test apparatus of Example 1, the design data (weight, center position, etc.) of the sled 15 and the tow board 25 can be obtained in advance by the actual vehicle collision test.

The position of the specimen 16 on the image is set to a predetermined value.
Then, as shown in Figs. 1 to 3, the piston 17a is punched out by hydraulically controlling the launching device 17, and the target forward and backward acceleration (sled ( 15) gives back acceleration in the specimen 16, and gives the specimen 16 the acceleration which simulates a collision time. Then, the sled 15 moves backwards by a predetermined distance with a given target back and forth acceleration.
In addition, by hydraulically controlling the launching device 26 simultaneously with the launching device 17, the piston 26a is punched out and the target front-back acceleration (to the toe board 25) with respect to the toe board 25 in the stopped state. The tow board 25 is given to the acceleration which simulates a collision time by giving back acceleration}. The tow board 25 then rotates backward by a predetermined angle with a given target back and forth acceleration. That is, as shown by the dashed-dotted line in FIG. 4, the tow board 25 has the inclined portion 25a as the middle portion (the support shaft 24) as a point, so that the angle θ1 becomes large and the horizontal portion 25b. ) Lowers the middle portion (support axis 24) as a point, and an angle θ2 is generated.
Thus, in the automobile collision simulation test apparatus of Example 1, it supports the sled 15 which can mount the specimen 16 so that it can move along a horizontal front-back direction, and the inclination part 25a extended upwards upwards, The middle portion of the tow board 25 having the horizontal portion 25b extending rearward is rotatably supported by the support shaft 24 at the front portion of the sled 15, and towed by the launching device 26. In the board 25, acceleration can be provided toward the rear of the inclination part 25a and below the horizontal part 25b.
Accordingly, by allowing the launching device 26 to impart an acceleration toward the rear of the inclined portion 25a in the tow board 25, and to provide an acceleration toward the lower portion of the horizontal portion 25b, The inclination part 25a and the horizontal part 25b of the tow board 25 are operated simultaneously, and the reproducibility in the automobile crash simulation test can be improved.
In addition, in the vehicle collision simulation test apparatus of the first embodiment, the tip of the inclined portion 25a is moved backward by the launching device 26, and rotational force can be applied so that the tip of the horizontal portion 25b moves downward. I'm letting you. Therefore, the deformation | transformation of the tow board 25 at the time of an actual automobile collision can be reproduced with high precision.
In the vehicle collision simulation test apparatus of Example 1, the inclined portion 25a and the horizontal portion 25b are integrally connected to each other via the intermediate portion of the tow board 25 and are rotatably supported by the support shaft 24. . Therefore, the structure of the tow board 25 can be simplified by integrating the inclined portion 25a and the horizontal portion 25b together.
