AI Technical Summary

Technical Problem

Existing technologies such as THUMS, GHBMC, and VIVA, used in automotive crash studies, cannot accurately predict the injury response of Chinese occupants in real-world crashes. In particular, existing technologies cannot accurately predict the injury response of obese Chinese occupants in automotive crashes.

Method used

A biomimetic model of injury in obese male occupants at the 50th percentile in China was constructed. By adjusting the spatial posture of the ribs, customizing the muscle and visceral structures, and adjusting the fat mass, a hybrid connection of pentahedral and hexahedral meshes was used to assign material properties to different parts, thereby achieving detailed anatomical structure and biomechanical characteristics.

Benefits of technology

It provides detailed anatomical structures and biomechanical characteristics, enabling accurate simulation of the injury response of obese Chinese occupants in car crashes, providing a data foundation for optimizing automotive safety protection systems and improving safety protection levels.

Abstract

The application discloses a method for constructing a Chinese 50th percentile male obese occupant injury bionic model, and the method comprises the following steps: step A: adjusting the chest cavity structure of a Chinese 50th percentile male occupant injury bionic original model according to the characteristics of an obese population; step B: based on the mass distribution characteristics of the obese population, increasing and adjusting the shape of the fat grid of the original model, so that the overall mass of the model meets the target range; step C: on the basis of the adjusted shape, reconstructing the fat grid and the skin structure, and realizing the common node connection between different parts, so as to obtain the Chinese 50th percentile male obese occupant injury bionic model. The application has wide application prospects.
