Problems solved by technology

Now for the calibration equipment of the dummy chest, the operator lifts the impact hammer to a certain height and releases it for the impact test. Due to the height, the general lifting height will be limited to less than two meters for the test, and the test range is small.
The lifting height of the impact hammer is also measured manually, and there is a large measurement error, which leads to low accuracy of the calibration experiment

Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings.

[0023] Such as Figure 1~3 As shown, a car crash test dummy chest calibration equipment includes an impact hammer mechanism 2 and a guide rail mechanism for hitting the dummy chest to be tested. The guide rail mechanism includes a base 7 and a guide rail 1 fixedly arranged on the base 7. The impact hammer The mechanism 2 is slidably arranged on the guide rail 1 along the length direction of the guide rail 1. The calibration device also includes an elastic member arranged between the impact hammer mechanism 2 and the guide rail mechanism and is separately connected with the impact hammer mechanism 2 and used to drive the impact hammer mechanism. 2 The drive mechanism that slides on the guide rail 1 to make the elastic member exert force on the impact hammer mechanism 2.

[0024] The elastic part is a spring 3, and the extension direction of the spring 3 is consistent w...

Abstract

The invention relates to vehicle crash test dummy chest calibration equipment, comprising an impact hammer mechanism for impacting a dummy chest to be tested and a guide rail mechanism, wherein the guide rail mechanism comprises a fixed guide rail, the impact hammer mechanism is arranged on the guide rail in a sliding manner along the length direction of the guide rail, and the calibration equipment further comprises an elastic part arranged between the impact hammer mechanism and the guide rail mechanism and a driving mechanism being in split connection with the impact hammer mechanism and used for driving the impact hammer mechanism to slide on the guide rail so that the elastic part produces an acting force on the impact hammer mechanism. The calibration equipment is not influenced by the height of an operator, and is wider in test range and high in accuracy.

Description

technical field [0001] The invention belongs to the technical field of automobile safety detection, and in particular relates to a chest calibration device for an automobile collision test dummy. Background technique [0002] In the field of automobile safety detection technology, automobile crash test is an important test method to test the safety performance of automobiles, and the test dummy, as the basic tool of automobile collision test, plays a vital role in the development of automobile safety. For the dummy in the crash test, in order to ensure the accuracy of the test data, it must be recalibrated before each experiment. For the existing dummy chest calibration equipment, the dummy is installed on the test bench with a bracket structure, and the impact hammer is connected to the bracket through a connecting rope. During the test, the tester lifts the impact hammer to a certain height, and then the operator The personnel measure the lifting height of the impact hamm...
