Strategies for Improved Vehicle Safety:

Survivability of Occupants

ABSTRACT

The Mechanics and Aerospace Design Laboratory at the University of Toronto has been engaged in research concerned with crashworthiness and automotive safety for two decades. In this presentation, I shall summarize our efforts and address occupants’ response to varied collision scenarios analytically, numerically and experimentally. The analytical is based on multibody dynamics, the numerical on dynamic elasto-plastic finite element and the experimental on crush and crash-worthiness tests of shock absorbers. Finite element model of a global human body is used to study occupant’s response during frontal, rear, frontal-to-rear and side collisions in car accidents. The research intends to show the effect of the different parameters on altering the dynamic response of the occupants with emphasis on their survivability using injury criteria. Specifically, the effect of deploying (or lack of) airbags, seat belt, head rest, occupant’s awareness and posture will be examined and their influence on occupants’ safety assessed. Additionally, the effect of the introduction of ultralight cylindrical and conical shock absorbers, filled with metallic foam or unfilled, in vehicles upon the reduction of the impact energy collisions is examined. I shall also examine future trends in automotive safety and occupants survivability.

ENHANCEMENT OF FATIGUE LIFE AND ELONGATION OF MATALLIC MATERIALS

BY HIGH-DENSITY PULSED ELECTRIC-CURRENT

ABSTRACT

Fatigue fracture is an extremely important phenomenon in metal structures because most mechanical components experience cyclic loads. Therefore, the improvement of long-term durability and reliability of mechanical structures is required against fatigue fracture. On the other hand, elongation is an important mechanical property of metallic materials which affect the formability of mechanical components, especially for high-temperature resistance materials. Therefore, it is necessary to develop a new method to enhance the elongation of metallic materials.

In this talk, I intend to introduce a new technique that can be used to enhance the fatigue life and elongation of metallic materials by applying a controlled, high-density pulsed current. Austenitic stainless steel, titanium-aluminum alloy and aluminum alloy were used as the test materials under the conditions of with and without fatigue crack, with and without prestrain, and standard. The effects of high-density pulsed current on the healing of fatigue crack, and the delay of crack initiation, as well as the recovery of plastic damage were investigated in detail. Furthermore, the effects of high-density pulsed current on the change of Vickers hardness, residual stress, and dislocation density, as well as crystal size and orientation of the materials were analyzed thoroughly in order to clarify the mechanism.

Professor Veit Senner

Professor of Sport Equipment and Sport Materials

Department of Mechanical Engineering

Technical University of Munchen

Email: senner@tum.de

Professor Veit Senner graduated from Technical University of Munich (TUM) with an academic degree in Mechanical Engineering in 1989. He continued studying at the same University and graduated 1995 with the second academic degree in Sports Science. At the same time Prof. Senner started his industrial career at TÜV SÜD, the German leading test-house. In 2000 Prof. Senner became Department Manager in the business unit Medical Health Sports. During his time in industry he continued to work on his University career, receiving his Ph.D in Mechanical Engineering (Dr.-Ing.) in 2001. One year later he has been appointed as Professor at TUM and took over the responsibility for the Division Sport Equipment and Materials. In 2009 this professorship was transferred to Mechanical Engineering where it became an associated division at the Chair of Ergonomics. Its research and teaching is clearly positioned between engineering and sports science. Professor Senner’s major research area is biomechanics related to human equipment interaction by means of computer simulation. Between 2005 and 2009 he has served as Associate Dean for the Faculty of Sport Science. Prof. Senner is President of Germany’s Interdisciplinary Association for Sports Technology (divers) and has served over six years as member of Executive Committee of International Sports Engineering Association. Since more than ten years he is Vice President of the International Society Skiing Trauma and Safety and since 2006 President of the Association Snow Sport Education at German Universities. He has published more than 100 articles in national and international journals as first and as co-author (75 listed in scopus), his actual h-index is 8. Currently he is supervising eight Ph.D students and 10 Master’s thesis. .

Safety in Sports: Challenges and Opportunities

ABSTRACT

The positive role of sports and physical activity to maintain health and well-being is not questioned. On the other hand we have to register a significant number of acute and also long-termed injuries which are related to practising sport. A good estimate for European countries is an injury rate of approximately 500 per 10.000 which would accumulate to 3,28 million sports related injuries in the UK.

Under the leadership of two well-known institutes, Oslo Sports Trauma Research Centre and the Research Centre for Physical Activity, VU Medical Centre, Amsterdam, the European College of Sports Science has published a consensus paper on the prevention of acute sport injuries. This research group sees the use of equipment designed to reduce injury risk at first position of the most successful prevention measures.

For this reason one major concern of our research is to improve protective equipment or even to develop new concepts. Further we also look at functionality and performance of sporting goods, because this is often also linked to safe operation. From a methodological standpoint, investigations in this field may become rather difficult because for ethical reasons experiments with subjects have to be ruled out. Instead we sometimes have to use mechanical (physical) and mathematical models to simulate the behaviour of (protective) equipment in safety critical situations.

The keynote presentation will give three examples of our research, the first in the field of footwear design applied to soccer and trail running. The second example illustrates the protection capacity of sport helmets and the third deals with opportunity of and the challenge to develop mechatronic ski bindings in order to reduce the number of knee injuries.
