Abstract

In a vehicle-collision simulation testing apparatus, to make it possible to downsize the apparatus with lightweight. A sled 11 is supported in a movable manner in a back-and-forth direction, a yawing sled 14 is arranged on the sled 11 in a horizontally rotatable manner with a front portion supported by a rotation shaft, on which a product under test can be mounted, an eccentric mass 17 is arranged on a side of a rotation shaft on the yawing sled 14, and a launching device 18 that applies a backward acceleration on a front side of the sled 11.

Description

technical field [0001] The invention relates to a motor vehicle collision simulation test device which reproduces the acceleration generated in the passenger compartment during the collision without destroying the motor vehicle, and reproduces the injury degree of the passenger caused by the secondary collision. Background technique [0002] Generally, in the crash test of motor vehicles, there are real vehicle crash tests for evaluating physical quantities such as the amount of collision or the remaining space of the passenger compartment, and passenger injury values. Experiments are very costly. Therefore, a body-in-white, dummy body, etc. (hereinafter referred to as "test body") equipped with a dummy, an airbag, etc. (hereinafter referred to as "test body") was mounted on a trolley, and the acceleration approximately the same as that of a real vehicle was applied to the trolley, so that The impact degree acting on the test object is non-destructively reproduced to evalua...
