Development of SAFER HBM v11

Report, 2024

The development of SAFER HBM started in 2008, when the first human body modelling (HBM) project was initiated by members of the SAFER - Vehicle and Traffic Safety Centre. The objective from the start was, and still is, to develop an “omnidirectional, tunable and scalable HBM capable of injury risk and biofidelic kinematics prediction in high-g as well as low-g events”. Up until 2017, the model was called SAFER THUMS, as up until that point the THUMS version 3 model was used, with add-on active muscles (Östh et al., 2012), and retuned material parameters of the chest (Mendoza-Vazquez et
al., 2013). As these modifications were carried out by different researchers in different projects, two versions were available, one version with muscle and muscle control system implemented, referred to as active SAFER THUMS for prediction of low-G kinematics, and a passive SAFER THUMS for kinematic predictions and injury evaluation in high-G loading.
