A 50th Percentile Female Human Body Model for Research on Equitable Occupant Protection

Authors: Takao Matsuda, Noriyuki Fujita, Mitsuaki Goto, Yuichi Kitagawa, Toyota Motor Corporation

Abstract

The application of virtual human body models in vehicle safety research has expanded significantly, providing advantages over traditional anthropomorphic test devices. Key advantages include the flexibility to adjust body shape and posture and the ability to accurately assess injury risk at the tissue level. In this study, a virtual human body model representing a 50th percentile female occupant was developed to enhance research on gender and sex in injury assessment. The model was generated by scaling the existing 5th percentile occupant model taking into account the anatomical features of the female skeleton. The mechanical properties of the developed model were validated by comparing with those measured in post-mortem human subject tests described in the literature. Vehicle frontal and lateral collision simulations were conducted using male and female occupant models of different body shapes. The injury risks were analyzed and compared between the models.
