Abstract

This paper deals with a demonstration of a six-year-old child model. The model, called Bobby, belongs to a family of human rigid body models, Robby, and was created within the computational environment of the PAM system. First of all, Bobby is updated, the geometry and material properties of the original model are improved, and, in particular, joints, including their characteristics, are redefined. The updated model is tested in a sled test environment. Due to lack of experimental data with child cadavers, the test is compared to an experiment with the six-year-old Anthropomorphic Test Device, published in available literature sources.

Highlights

That the safety of child car passengers is still a current topic is demonstrated by the following facts
Since no experimental data of a six-year-old (6YO) boy are available, the Bobby sled test simulation is compared to the results presented in Malott et al (2004) where the sled test with a six-year-old Anthropomorphic Test Device (ATD) is performed
The segment generally includes bearing bones and a particular part of skin. It is characterized by its center of gravity (COG), mass and inertia properties taken from Morille, (2001)

Summary

Introduction

That the safety of child car passengers is still a current topic is demonstrated by the following facts. According to the European Child Safety Alliance, road traffic injuries are the leading cause of death and severe injuries among children aged 0–14 years, and are the cause of 34% of child injuries and deaths annually. Most of the research uses dummy models (Malott et al 2004; Palisson et al 2007; Paine, 2001). Human models are becoming more precise and more biofidelic (Haug et al 2004; Číhalová, 2009) with the ability to understand human body behavior, and are able to describe injury analysis in more detail. The research community tends towards the legalization of human body models in the car industry (Haug et al 2003)
