Specification-adjustable dummy used for car crash testing

Abstract

A specification-adjustable dummy used for car crash testing comprises a skull, a neck, upper arms, lower arms, hands, a jacketed upper body assembly, a butt, thighs, shanks and feet, and balancing weights are arranged on end covers of the skull, the neck, the upper arms, the lower arms, the hands, the jacketed upper body assembly, the butt, the thighs, the shanks and the feet. The specification-adjustable dummy used for car crash testing has the advantages that a structure is simple, manufacturing cost is low and testing cost is lowered by means of substituting dummies with HIII50th balancing weights and HIII95th balancing weights in vehicle testing; an application range is wide, specifications are adjustable, and applicability to tests in different specifications is achieved by means of balancing weight adjustment; mounting and dismounting are facilitated, and since no skins are arranged on the arms and the legs, mounting, dismounting and transportation of the dummy are more convenient; test can be implemented during dynamic response in a testing process; the degree of rotating tightness in each dummy body joint part is highly adjustable, the dummy can be fixed by a safety belt, and the safety belt and other interior trims in a car cannot be damaged during crashing.

Description

technical field [0001] The invention belongs to the field of automobile safety testing, and in particular relates to a collision model used for simulating human body structure in a collision test. Background technique [0002] Due to the danger of the crash test, automobile safety crash models, i.e. dummies, are used as test tools at home and abroad. HⅢ50th and HⅢ95th dummies are often used in crash tests. However, some crash tests only need to balance the weight of the whole vehicle during the test process. , there is no need to collect a large amount of collision data, so using the high-cost HⅢ series dummies in this part of the test will often cause unnecessary waste. [0003] In the prior art, it has not been possible to replace the dummies of HⅢ50th and HⅢ95th with a lower-cost dummy, and there is no dummy that can simulate different human body weights for the vehicle crash test. Contents of the invention [0004] The technical problem to be solved by the present inv...
