Jobbannons

Join a group that develops two of the most advanced Human Body Models on the market today, the SAFER HBM and the open source VIVA+ HBMs.

Join a group of researchers and PhD-students that work in projects with partners from the vehicle industry known with be in forefront in the passive safety research field.

Join a team that have collaborated with CAE-software developers for years.

Information about the division and the department

The research at the Division of Vehicle Safety investigates why and how often accidents and incidents occur, driver reactions in different traffic situations, and how injuries occur. The Injury Prevention (IP) group is responsible for investigating the injury mechanisms at the micro- to macroscopic levels as well as the dynamic response of the whole human body to externally applied mechanical loads. In 2009, the IP group initiated research activities in the field of Human Body Modelling (HBM) in close collaboration with the industry and SAFER - The Vehicle and Traffic Safety Center at Chalmers. Today, the research at IP mainly focus on the development of HBMs representative of the entire population that can predict the risk of all types of injuries in traditional as well as in novel seating positions. This research is carried out in close collaboration with the Swedish vehicle industry, other Universities, research institutes, government agencies, and insurance companies.

Major responsibilities

With increasing vehicle automation and shared mobility solutions, occupant sitting postures and activities are expected to vary more than in today's vehicles. Development of protection systems adapted for this increases the requirements on the tools that are used. Virtual Human Body Models (HBMs) such as the SAFER HBM have the potential to fulfill these requirements and predict human response and injury risk. Through morphing capabilities, SAFER HBM can represent both women and men of various age, stature, and Body Mass Index (BMI).

The future sitting postures such as reclined alters the kinematics of the occupant in crashes. The loads on the upper and lower torso are altered relative to today's sitting postures which leads to new and added challenges for the restraint system. One of the challenges are to model the pelvis to belt interaction to reduce the pelvis and abdomen injury risk.

Therefore this project aim at improving the biofidelity and torso injury risk prediction capabilities of the SAFER HBM for a variety sitting postures, injury severity levels, across a range of crash situations addressing all vehicle occupants. Project goals include enhancing injury predictions, by including pelvis fracture risk prediction for both female and male occupants of different age and BMI. This means that the morphing capabilities will be further enhanced, and that sex, age and BMI will be considered when developing injury risk functions.

In brief the aim is to develop injury criteria and/or risk functions for pelvis fractures.
