Human Body Model Morphing for Safety Assessment Across Occupant Variability and Seating Postures

Research Project, 2026 – 2030

The purpose of the project is to enable robust population-level vehicle safety assessment by creating a coherent full-body human body model (HBM) morphing framework that captures sex, body size, obesity and posture differences. The goals are to create female/male reference anthropometries, build an external body-surface model linked to skeleton and posture, integrate both into one transparent morphing method, and demonstrate effects on occupant kinematics and injury metrics.

The Expected results are; full-skeleton and body-surface statistical shape models, a unified HBM morphing method, and demonstrations with SAFER HBM showing effects on occupant kinematics and injury metrics. The expected impact is more inclusive virtual safety assessment for varied body types and postures, support for automated/shared vehicle design, reduced reliance on external methods, and improved Swedish competitiveness in vehicle safety.
