Dummy neck calibration device and dummy neck calibration method

Abstract

The invention provides a dummy neck calibration device and a dummy neck calibration method, wherein the dummy neck calibration device and the dummy neck calibration method are in the field of an automobile. The device is used for being mounted on a pendulum calibration system for calibrating the neck and comprises the components of a pendulum connecting component which is mounted at a swinging arm end of a pendulum calibration system; a neck component of which the top connecting end is fixed to the lower surface of the pendulum connecting component; a head component assembly of which the mass center is same with the mass center of the simulated dummy head and comprises a headform component and a head-and-neck connecting component, wherein the head-and-neck connecting component can be connected with the neck component and the headform component so that the bottom connecting end of the neck component can be linked with the headform component; and an angle measuring mechanism which is mounted on the dummy neck calibration device. The dummy neck calibration method is applied to the dummy neck calibration device. The head component assembly replaces an original dummy head, thereby preventing dummy head loss in a neck calibration experiment and preventing accuracy reduction of the calibration experiment.

Description

technical field [0001] The invention relates to a dummy crash test device in the automobile field, in particular to a dummy neck calibration device and a calibration method. Background technique [0002] In the car crash test, the dummy is an important equipment in the crash test. In order to ensure the accuracy and reliability of the data obtained in the crash test, it is necessary to calibrate the crash dummy once every two crash tests. In the prior art, when calibrating the neck of a dummy, a pendulum calibration system is generally used, and the system includes a bracket, a swing arm, and an energy-absorbing device. One end of the swing arm is installed on the bracket, and the head and neck of the dummy is removed and fixed on the other end of the swing arm. Then raise the swing arm to a certain height, release the swing arm, and move the swing arm to the vertical position to collide with the energy-absorbing device. During the impact, the head and neck bear a certain ...

AI Technical Summary

Problems solved by technology

The dummy equipment itself is very expensive, but in the calibration test of the existing technology, the head and neck of the dummy will be impacted, which increases the loss of the dummy's head and neck to varying degrees

In addition, if the data obtained in the calibration test is inaccurate, it will also affect the accuracy of the subsequent crash test
