Problems solved by technology

However, in a real car crash test scene, each part of the dummy will be subjected to different impact loads, and the performance technical requirements of the dummy components obtained based on the existing performance limit value construction method cannot be truly, accurately and effectively evaluated. The technical performance of each part of the dummy actually applied in complex collision scenarios
At present, there are no performance limit requirements for dummy components under various crash impact tests at home and abroad

Abstract

The invention relates to the field of automobile passive safety testing, in particular to a method for constructing impact response performance limits of a collision dummy and electronic equipment. The method includes: according to the response curves of the crash dummy under different impact test conditions, determining the standard response curve and the alignment start and end times of each response curve; according to other response curves except the standard response curve and the For the difference between the standard response curves, align other response curves except the standard response curves with the standard response curves; determine the impact response performance limit function of the crash dummy according to all the response curves after alignment; Wherein, the difference includes cumulative difference or cumulative variance. This method can truly, accurately and effectively construct the performance limits of dummy components under various impact tests.

Description

technical field [0001] The invention relates to the field of automobile passive safety testing, in particular to a method for constructing impact response performance limits of a collision dummy and electronic equipment. Background technique [0002] Automobile crash test is the technical core of evaluating vehicle safety performance, and crash dummy is the key test equipment directly used in the evaluation of automobile safety performance instead of occupants. The impact response performance of each part of the crash dummy directly affects the results of automobile safety performance evaluation. The impact test for each part of the dummy is a technical way to test the performance of the dummy. Comparing the output of the impact test response of each part of the dummy with the existing performance limit requirements is a key technical means to evaluate the performance of the dummy. [0003] At present, one test condition is used for performance evaluation of each component o...
