Abstract

The present invention provides a vehicle crash simulation test device and method thereof, and a control device for the vehicle crash simulation test device, so that the reproducibility can be improved. In the vehicle crash simulation test device, a pulley (11) capable of mounting a test body (15) is supported so as to be movable in a horizontal front-rear direction, and is provided as a launching device (21) capable of applying acceleration to the pulley (11). There is a hydraulic cylinder (22) capable of driving the piston (32) toward the pulley (11), an accumulator (23) connected to the rear chamber (B) side of the hydraulic cylinder (22), and an accumulator (23) provided in the hydraulic cylinder (22) The servo valve (24) on the discharge port (45) formed by the front chamber (A) of the front chamber (A), and the driving start position setting mechanism for setting the driving start position of the piston (32) based on the data obtained through the actual vehicle crash test is provided. .

Description

technical field [0001] The present invention relates to a motor vehicle collision simulation test device and its method, and a control device for the motor vehicle collision simulation test device, which can reproduce the acceleration generated in the passenger compartment during the collision without destroying the motor vehicle, and reproduce the injury degree of passengers 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-destruc...
