Abstract

The present invention makes it possible to enhance the reproducibility of a device for automobile collision simulation testing. This servo actuator for automobile collision testing thrusts a piston rod toward a sled which is supported so as to be movable along a horizontal back-and-forth direction and upon which an object to be tested can be placed. The servo actuator for automobile collision testing is provided with a fluid cylinder into which the piston rod has been inserted, an accumulator that is connected to the opposite side of the fluid cylinder from the sled side and accumulates hydraulic oil to be supplied to a hydraulic actuator, a servo valve provided at a discharge port formed on the sled side of the fluid cylinder, and a position adjustment mechanism that abuts the end of thepiston rod opposite from the sled side, restricts movement toward the accumulator side, and is capable of adjusting the end of the accumulator-side movement range of the piston rod.

Description

technical field [0001] The present invention relates to an automobile collision simulation test device which reproduces the acceleration generated in the passenger compartment during a collision without destroying the automobile, and reproduces the injury degree of the occupant caused by the secondary collision. Background technique [0002] Generally, in the crash test of automobiles, there is a real car crash test for evaluating physical quantities such as the amount of impact, the amount of remaining space in the passenger compartment, and the value of occupant injuries. The method of collision is to destroy the test, which requires a high cost. Therefore, by attaching a body-in-white, dummy body, etc. equipped with a dummy, an airbag, etc. to a trolley, and giving the trolley approximately the same acceleration as when the real vehicle collides, the impact on the test piece can be reproduced in a non-destructive manner. The degree of impact and the evaluation of occupan...
