A mapping method for evaluating the degree of human impact injury based on animal injury condition equivalence

By constructing a multi-species biomechanical model and combining it with principal component analysis, a cross-species damage mapping method was established for underwater explosion vibration and shock environment. This method solves the problem that existing technologies cannot assess damage to multiple organs throughout the body and enables accurate assessment of the degree of human injury.

AI Technical Summary

Technical Problem

Existing mapping methods are not applicable to underwater explosion vibration and shock environments and cannot effectively assess damage to multiple organs throughout the human body, especially for underwater explosion vibration and shock, a significant injury-causing scenario.

Method used

A multi-species, high-fidelity biomechanical finite element model of a beagle, a Bama pig, and a human was constructed. Underwater explosion vibration impact loads were applied, and damage modes were obtained through simulation. Principal component analysis was performed in conjunction with a simplified damage grading standard and a new damage severity scoring system to establish a mapping relationship between scaling factors and damage severity scores.

Benefits of technology

It enables scientific assessment of damage to multiple organs of the human body under underwater explosion vibration and impact environment, provides targeted technical support, and offers a complete technical solution for impact safety assessment, development of protective equipment, and medical treatment of injuries.

Abstract

The application discloses a mapping method for evaluating human body impact damage degree based on animal injury condition equivalence, and belongs to the technical field of impact damage biomechanics, and comprises the following steps: constructing a whole-body high-fidelity biomechanical model of different species, applying underwater explosion vibration impact loads with different intensities to the model to obtain damage modes; statistically classifying the damage modes, integrating the damage modes to form a damage database, quantitatively calculating the damage in the damage database by using a new damage severity scoring system, selecting multiple physical factors affecting the biological damage degree, screening out two key physical quantities with the highest contribution rate to define scaling coefficients, and drawing a mapping atlas for evaluating the human body impact damage degree based on animal injury condition equivalence; the mapping atlas of the injury condition across species is established by constructing the multi-species biomechanical model and combining principal component analysis, and the accurate evaluation from animal experimental data to the human body damage degree under the underwater explosion vibration impact environment is systematically realized.
