Embodiment Construction

[0055] Use the following Figure 1 to Figure 8 Embodiments of the present invention will be described. here, figure 1 It is an overall configuration diagram showing the first embodiment of the crash test apparatus of the present invention. in addition, figure 2 Yes figure 1 The enlarged view of the reduction gear shown, (A) is a side view, (B) is figure 2 (A) is the view from direction B, (C) is figure 2 (A) C-C cross-sectional view.

[0056] like figure 1 and figure 2 As shown, the crash test device of the present invention has a test body 1 on which a dummy 11 simulating a passenger is placed, a driving device 2 for making the test body 1 advance, and a deceleration device 3 for decelerating the test body 1 by collision. The deceleration device 3 There is a buffer part 31 colliding with the test object 1, a shaft part 32 having the buffer part 31 at the front end and extending along the advancing direction of the test body 1, a main body part 33 supporting the sh...

Abstract

The present invention provides an impact test device and an impact test method which can easily reproduce impact. The impact test device of the invention is provided with the following components: a test member (1) which carries dummies (11) for simulating passengers, a driving device (2) which causes the test member (1) to advance, and a speed reduction device (3) which causes the impact of the test member (1) for reducing speed. The speed reduction device (3) is provided with the following components: a buffer part (31) which impacts with the test member (1), a shaft part (32) which is provided with the buffer part (31) at the front end and extends along the advancing direction of the test member (1), a body part (33) which supports the shaft part (32), a brake device (34) which is configured at the body part (33) and applies the load in a direction which is approximately same with the advancing direction of the test member (1) on an external surface of the shaft part (32), and a control device (35) which controls the load that is applied by the brake device (34).

Description

technical field [0001] The present invention relates to a vehicle crash test device and a crash test method, and more particularly to a deceleration type crash test device and a crash test method for decelerating a test body by colliding with it. Background technique [0002] In the technical development of vehicles such as automobiles, the safety of the vehicle is evaluated by observing the conditions and loads of the occupants when the vehicle collides by using a crash test device that simulates the state of a vehicle crash. There are acceleration-type and deceleration-type crash test devices, and the deceleration-type crash test device is generally composed of a test body on which a dummy simulating a passenger is placed, a drive device for moving the test body, and a collision test body with the test body. The structure of the speed reducer for deceleration (for example, refer to Patent Document 1 or Patent Document 2). [0003] In the crash test device described in Pat...
