Abstract

This application provides a method for occupant road traffic accident injury prediction. By selecting research parameters to form an occupant injury impact simulation matrix, the main effect and interaction effect of each influencing parameter can be analyzed, the coupling analysis between parameters is realized, and the damage prediction is improved. output precision. Through parametric finite element modeling, the accident simulation model under any working condition can be obtained, and the variables can be controlled in the research, and only the influencing parameters to be studied can be changed under the condition that most of the parameters are fixed, which makes up for the individual differences in the accident data Large, lack of uniform standards for parameter extraction. In addition, the finite element modeling is convenient and fast, and provides a database for the development of damage output prediction algorithms. The damage output through finite element simulation can be refined to each body part, which will help provide more direct and detailed damage prediction results in future traffic assistance.

Description

technical field [0001] The present application relates to the field of human injury assessment, in particular to a method for predicting occupant injury in road traffic accidents. Background technique [0002] In recent years, research on occupant injury prediction in road traffic accidents is mostly based on regression fitting of road accident statistics. Take the accident automatic emergency call system used on some cars as an example (advanced automatic collision notification, AACN). The core technical issue of this system is the development of damage prediction algorithms. Most of the current algorithms are based on accident statistics. The database of the transportation department performs regression fitting of damage and accident parameters. Analysis based on accident data usually satisfies objectivity. The AACN system is installed on the vehicle and can obtain real-time vehicle condition information, such as seat belt wearing status, vehicle speed, and the number of...
