The University of Agder has more than 1300 employees and 13 000 students. This makes us one of the largest workplaces in Southern Norway. Our staff research, teach and disseminate knowledge from a variety of academic fields. Co-creation of knowledge is our common vision. We offer a broad range of study programmes in many fields. We are situated at two modern campuses in Kristiansand and Grimstad respectively.
We are an open and inclusive university marked by a culture of cooperation. The aim of the university is to further develop education and research at a high international level.
The University of Agder invites applications for a PhD fellowship in Vehicle Crash – structural design and crashworthiness analysis of road vehicles. The position is linked to the Department of Engineering Sciences and the contract is for a period of 3 years. Starting date as early as possible/negotiable with the faculty.
The Department of Engineering Sciences has more than 110 employees in scientific positions, and more than 1300 students at all levels. A variety of research is being conducted within all the groups Mechatronics, Renewable Energy, Civil Engineering and Industrial Economy, and we also welcome interdisciplinary projects within the department or with other research groups. We have a broad international cooperation and we have a close cooperation with industrial partners and public services in the region. This is a benefit both to teaching and research. The partners contribute with assignments, competence and resources.
Brief Description of the Research Project
The number of vehicles in the world are increasing and so are the number of accidents too. Therefore it is very important to design the vehicles as safe as possible, both for the driver and the passenger, but also for the pedestrians. Much efforts have been done in testing new concepts and new vehicles before they are available in the marked. But doing such full-scale testing is both time-consuming, expensive and require sophisticated infrastructure. In the last three decades explicit Finite Element Models have been popular, but this is also time-consuming methods and require sophisticated infrastructure and heavy computers.
In this project we want to do numerical modelling and simulation by developing mathematical models for reconstruction of vehicle crash. These models may later be of interest also in the design process. Lumped Parameter Models (LPM) are using lumped masses to represent parts of the vehicle, e.g. engine block and the passenger compartment. These two parts are considered rigid during the analysis, and springs are representing the deformable structural elements. Models for the dynamics of a two-mass system with piecewise linear approximations for spring and dampers the genetic algorithm and parameters of a vehicle-to-vehicle frontal crash has been developed. More sophisticated models results in larger equation systems.
It is well known that coupled oscillators demonstrate a wide range of interesting mathematical phenomena, including sensitive dependence on initial data, bifurcations, synchronization, cooperative dynamics, multimode oscillations, chaos, to mention a few. Therefore, mathematical analysis of such models with rich dynamics using analytical tools from qualitative theory of differential equations and dynamic systems is both challenging and rewarding. One may, in particular, study stability properties and synchronization for such systems since these are particularly important for the modeling of mechanical systems. The list of methods used for studying nonlinear oscillations includes a variety of advanced techniques such as, for instance, averaging, linearization, harmonic balance, homotopy perturbation, iteration, parameter expansion, variational iteration, etc.
Research Topics for the PhD Research Fellow
The objective of the research is to establish new modelling techniques for reconstruction of vehicle crash. Such models should also have potential for included in the design process.
The potential topics for the PhD research fellow include, but are not limited to:
- Vehicle crash mathematical modeling, model validation and computer simulation
- Large equation systems, validated by building a model using advanced state-of-the-art tools (SimReal, equation-based languages)
- Prediction of vehicle and passenger response in computer impact simulation
- Analysis of response of materials, body structures and energy-absorbing systems subjected to sudden dynamic loading
- Crashworthy safety barrier design
- Model validation through co-simulation with hardware in the loop
- Developing more efficient and precise modelling
