CEVT is an innovation and development company at the forefront of mobility. Modular development, ground-breaking virtual engineering, software development and continuous innovation enable us to deliver world-class technology. Today we deliver to different automotive brands in the Geely family such as Geely Auto, Volvo Cars, and Lynk & Co and are based at Lindholmen in Gothenburg.
Master Thesis Project
Title: Crash simulations with a Human Body Model - HBM
Subject: Safety simulations
CEVT covers all aspects of passenger car development – from the total architecture, powertrain and driveline components, to top hat engineering as well as the vehicles’ exterior design. The company is located in Gothenburg & Trollhättan with close cooperation with Geely in Hangzhou and Cixi in China. The Safety department is responsible for developing vehicle safety performance to meet legal and consumer rating requirements. We work with many CAE tools but the focus is on LS-Dyna and Ansa/Meta.
Traditionally crash test dummies have been used to evaluate occupant protection in car crashes. In recent years finite element human body models (FE-HBMs) have become popular as a complement. FE-HBMs are models of humans, modeling the skeleton, joints and soft tissues in great detail. This means that it is possible to predict injury all the way down to tissue level. By design, HBMs are omnidirectional, meaning that they can be used for any load condition (e.g. frontal, side or oblique loads). In contrast, crash test dummies are unidirectional. This means that HBMs are superior for reconstructions of real-life crashes, as these often have a complex loading scenario.
This project will focus on implementing a (in the near future) relevant crash load case, using a state-of-the-art HBM (VIVA+ HBM) and a CEVT developed car structure, with the aim of providing guidelines how HBMs can be used to further enhance future car development. You will learn to use the state-of-the-art preprocessor ANSA as well as the explicit FE solver LS-DYNA.
HBM – Human Body Models. Today crash dummies are used to investigate many safety aspects regarding occupants in car crashes. Many questions about real-world injuries can not be answered by test dummies, instead, models of human bodies are needed.
This project will focus on implementing a crash load case with an HBM in a car structure and investigate how it can be utilized in future development. The HBM in this project is a VIVA+ model which is an improved VIVA model of a 50% female person.
