Problems solved by technology

Therefore, due to the disposition of the hydraulic cylinders, pumps, accumulators, etc. on the trolley, the weight balance will be disrupted, and the trolley will behave differently from the actual collision during the vehicle crash simulation test, and the reproducibility may decrease.

Abstract

The invention provides a vehicle crash simulation test apparatus which enables reproducibility to be improved. In the vehicle crash simulation test apparatus, a sliding vehicle (15) that allows a to-be-test body (16) to be carried is supported to freely move back and forth along a horizontal direction, and a pedal (22) is supported by the front portion of the sliding vehicle (15) to freely rotate. In addition, acceleration can be applied to the pedal (22) by an emission device (23) serving as an acceleration device. The components of the pedal (22) and the components of the emission device (23) are configured in a way that the central position on the left and right directions of the sliding vehicle (15) is arranged to be a gravity position.

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, the body-in-white and the simulated body, etc., equipped with dummy, airbag, etc. are mounted on the trolley, and the acceleration approximately the same as that of the real vehicle is applied to the trolley, so that the impact degree acting on the test body is non-destructive. Car crash simulation tests for the development of safety devices such as airbags are carried ...
