Master Thesis Project
Title: Analysis of seat and ride comfort using virtual analysis tools
Ride comfort is an area of increasing interest, especially as the automotive industry is paying more attention to future technology and sustainable development. The influences of vibration, ride motion and seat, plus their combined effects have been emphasized in previous laboratory and field studies. To assess seating comfort in an early stage of car design, numerical simulations such as the Finite Element Method (FEM) have also been widely applied. In this thesis work, a numerical approach to the analysis of vibration and contact pressure on the passenger car occupant arising from real excitations from the whole vehicle will be investigated. The FE-model of the human body will be developed and integrated with a passenger car seat model for the analysis.
As a Master thesis student, you will be working on developing a human body FE-model that could be integrated with the car seat model and could represent the vibration transmitted to various parts of the human body, as well as the contact pressure between the seat and the human body. You will be working with engineers across our vehicle development teams (e.g., vibration, vehicle dynamics, seat, CAE, etc.), as the different teams hold separate attribute responsibilities.
The overall aim of this thesis work is to develop an anthropometry-detailed numerical methodology for dynamic ride comfort analysis. The aims are to develop an integrated FE-model of the human body and car seat, to analyze the local vibration at the head and arm plus the whole-body vibration transmitted from the seat. The contact pressure between seat and occupant (e.g., lower thighs and back) will also be investigated.
