Problems solved by technology

However, in the existing calibration equipment, the operator uses a measuring stick to measure the height of the pendulum, which not only has inaccurate measurement accuracy and inconvenient operation, but also has the problem of large artificial measurement errors, which leads to inaccurate calibration tests. precise
In addition, when the lifting mechanism of the existing foot calibration equipment releases the pendulum, it is released through power failure. This release method has great potential safety hazards. Danger

Abstract

The invention relates to an automotive crash test dummy foot calibration device, which comprises a test bed for mounting a dummy foot, a support disposed on the test bed, a bob disposed rotatably on the support and used for colliding with the dummy foot mounted on the test bed, a lifting mechanism disposed on the support and used for lifting the bob, and a control system for controlling the bob to be lifted to a required height. The control system comprises a display panel for real-time display of the height of the bob. According to the invention, the calibration device can display the height of the bob in real time via the display panel, and help the staff read out the height position of the bob clearly, thereby accurately controlling the release of the bob.

Description

technical field [0001] The invention belongs to the technical field of automobile safety detection, and in particular relates to a device for calibrating the foot of 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. In the prior art, the equipment for calibrating the dummy foot adopts a test platform and a bracket structure. The dummy foot is installed on the test platform, and a pendulum and a pendulum lifting mechanism are installed on the bracket to rotate. By releasing the pendulum, the pendulum Collide with the dummy foot to complete the impact test...
