Individualized Morphing of Human Body Models for Biomechanical Analysis in High-G Environments

This study focuses on the development of morphing techniques to create individualized body models for biomechanical analysis in high-G environments, such as those encountered by fighter pilots. Traditional human body models often lack the ability to represent individual variability in body dimensions and biomechanics, limiting the accuracy of predictions regarding spinal stress and injury. To address this limitation, the Toyota Human Model for Safety (THUMS) finite element model was used as a baseline to develop a morphing framework. This framework allows for the generation of individualized models by scaling and reshaping the baseline geometry to represent anthropometric variability across the 50th, 80th, and 98th percentiles. The morphing process preserves mesh quality and the biomechanical integrity of the original model. The new models were not subjected to force simulations, the morphing framework successfully demonstrated its capability to capture critical variations in body morphology and biomechanical properties. These individualized models are designed to enhance future analyses by providing a foundation for simulating how different body types respond to high-G environments. This work demonstrates the relevance of personalized models in aerospace medicine and provides a foundation for future studies to use these models to examine injury risks. Future steps include applying high-G forces to the models to improve predictions of spinal health outcomes and inform injury prevention strategies.
