A Method for Evaluating the Biosimilarity of Dummies in Crash Tests

Abstract

The invention provides a method for evaluating the degree of biological simulation of a dummy in a collision test, and divides the quantitative indicators of the biological simulation of the dummy into three levels: the first-level indicators are the quantitative index values ​​of the biological simulation of each part of the dummy The second-level index is the simulation quantitative index value of the injury index corresponding to each part of the dummy; the third-level index is the simulation quantitative index value of each injury index quantified from different dimensions. The invention is a method for evaluating the degree of biological simulation of a dummy in a collision test, which correlates the calibration test results of the dummy under the same test conditions with the known real human body reference injury data, and uses single value analysis and time domain curve analysis In the two methods, the biosimilarity index of each part of the dummy is quantified, and each sub-indicator is further weighted and calculated, and finally the index value used to evaluate the overall biosimilarity of the dummy is obtained.

Description

technical field [0001] The invention belongs to the field of automobile crash tests, and in particular relates to a method for evaluating the biological simulation degree of a dummy in a crash test. Background technique [0002] In the car crash test, the crash test dummy, as a substitute for a real person, undertakes the function of measuring human injury during the collision process. It mainly measures various physical signals through various sensors installed inside to represent the impact of the car on the human body during the collision process. Therefore, the dummy in the crash test is an important measurement equipment to directly evaluate the safety performance of the car, and the biosimilarity of the dummy is directly related to whether the safety of the vehicle can be evaluated correctly, and thus also affects Whether the life and property of occupants or pedestrians can be effectively protected, so it is an important content in the study of automobile crash tests ...

AI Technical Summary

Problems solved by technology

[0003] Under the current technical conditions, the evaluation of the biological simulation degree of each part is generally carried out by the calibration test of each part of the dummy, and there is a lack of evaluation method for the overall biological simulation degree of the dummy in the crash test, which mainly has the following three problems: First, The calibration test of each part of the dummy cannot obtain quantitative results, but can only obtain qualitative evaluation results of conformity and nonconformity; second, there are multiple sensors in each part of the dummy, so multiple data channels will also be obtained in the calibration test and injury indicators, but currently each indicator is independently judged, and the overall situation of the dummy parts is not evaluated; third, the calibration test of each part of the dummy is relatively independent, and the comprehensive evaluation results of the biological simulation degree of the entire dummy cannot be obtained , to sum up, the current evaluation of the biological simulation of dummies lacks a quantitative evaluation method for the overall evaluation of crash dummies, and the biological simulation of different dummies cannot be directly compared horizontally, which ultimately leads to inaccurate evaluation of the results of automobile crash tests.
