[0002] Usually, in terms of automobile crash tests, there are real car crash tests for evaluating physical quantities such as the amount of collision or the amount of remaining space in the car, and the value of occupant damage. The method of collision is a destructive test and the cost is very high

Embodiment Construction
[0037] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. It should be noted that the present invention is not limited by this example.
[0038] (Configuration of vehicle crash simulation test device)
[0039] figure 1 It is a schematic diagram showing the configuration of the automobile collision simulation test device according to the present embodiment of the present invention.
[0040] In the automobile collision simulation test device of the present embodiment, as figure 1 As shown, the trolley 11 is a frame member having a plate of a predetermined thickness, and is formed in the front-rear direction (in the figure 1 The center is a long rectangular shape. A pair of left and right guide rails 13 having a predetermined interval are attached to the floor 12 in the front-rear direction, and the trolley 11 is movably supported along the guide rails 13 via sliders 14 fixed to the lower surface.

The objective of the present invention is to reflect the effects of pre-crash braking easily and appropriately. This test condition setting method for an automobile collision simulation test includes:an actual vehicle test result acquiring step of acquiring information relating to the relative position of a head portion of a dummy mounted in an actual vehicle relative to the actual vehicle, at the time the actual vehicle collides with an obstacle in an actual vehicle collision test or at a prescribed timing prior to the collision, and information relating to a change in the acceleration of the actual vehicle when the actual vehicle has collided with the obstacle; and a test condition setting step of setting test conditions on the basis of the results acquired in the actual vehicle test result acquiring step, in such a way that a sled acceleration waveform in the automobile collision simulation test includes a pre-crash waveform from a first time point to a second time point, and a collision waveform from the second time point. In the test condition setting step, the test conditions are set in such a way that the pre-crash waveform is a waveform based on the relative position information, and the collision waveform is a waveform based on the information relating to the change in acceleration.
Description
technical field [0001] The present invention relates to a test condition setting method for automobile collision simulation test and a test condition setting system for automobile collision simulation test, which can reproduce the acceleration generated in the compartment during collision without destroying the automobile, and reproduce the acceleration caused by the secondary collision degree of injury to the occupants. Background technique [0002] Generally, in the case of automobile crash tests, there is a real car crash test for evaluating physical quantities such as the amount of collision or the amount of remaining space in the car, and the value of occupant damage. The method of collision is a destructive test, and the cost is very high. Therefore, a car crash simulation test is carried out in which a body-in-white, a dummy body, etc., equipped with a dummy, an airbag, etc. On the other hand, the value of occupant injury is evaluated by non-destructively reproducin...
