The main objective of this thesis is to develop a computational human musculoskeletal model to investigate the change in the kinematic behavior of the model's lower extremities under the influence of activated (active) and deactivated (passive) muscles during a representation frontal collision using OpenSim software. Since OpenSim is seldom used in crash simulations, an appropriate model evaluation is performed by comparing the model's kinematics, obtained from the OpenSim's inverse dynamic simulation, against LS-DYNA's explicit non-linear side impact simulation of a finite element model for a car-pedestrian collision. The required musculoskeletal model is constructed in OpenSim and scaled to meet the requirements of the Hybrid III 50th Percentile crash test dummy. For evaluating the developed model, the kinematics from both programs (OpenSim and LS-DYNA), containing identical displacement data, is compared by visual observation of identical time frames. Using the evaluated model in the forward dynamics domain of OpenSim, a representative frontal crash simulation is conducted for the active and passive muscle states of the model, and the kinematic difference in its lower extremities is observed and compared. The results were also compared to MADYMO's human body model simulations conducted under similar conditions. This study indicates that the role of the muscle activation on the human body responses during a car collision is important. The novel technique developed and utilized in this study is shown to be quite useful in modeling and simulation of a car occupant's real kinematic response during a car collision.
Kinematics is an exciting area of computational mechanics which plays a central role in a great variety of fields and industrial applications. Apart from research in pure kinematics, the field offers challenging problems of practical relevance that need to be solved in an interdisciplinary manner in order for new technologies to develop. The present book collects a number of important contributions presented during the First Conference on Interdisciplinary Applications of Kinematics (IAK 2008) held in Lima, Peru. To share inspiration and non-standard solutions among the different applications, the conference brought together scientists from several research fields related to kinematics, such as for example, computational kinematics, multibody systems, industrial machines, robotics, biomechanics, mechatronics and chemistry. The conference focused on all aspects of kinematics, namely modeling, optimization, experimental validation, industrial applications, theoretical kinematical methods, and design. The results should be of interest for practicing and research engineers as well as Ph.D. students from the fields of mechanical and electrical engineering, computer science, and computer graphics.

The first International Congress on Science and Skiing was held in Austria in January 1996. The main aim of the conference was to bring together original key research in this area and provid an essential update for those in the field. The lnk between theory and practice was also addressed, making the research more applicable for both researchers and coaches. This book is divided into five parts, each containing a group of papers that are related by theme or disciplineary approach. They are as follows: Biomechanics of Skiing; Fitness testing and Training in Skiing; Movement Control and Psychology in Skiing; Physiology of Skiing and Sociology of Skiing. The conclusions drawn from the conference represent an invaluable practical reference for sports scientists, coached, skiers and all those involved in this area.

This book analyzes several compliant contact force models within the context of multibody dynamics, while also revisiting the main issues associated with fundamental contact mechanics. In particular, it presents various contact force models, from linear to nonlinear, from purely elastic to dissipative, and describes their parameters. Addressing the different numerical methods and algorithms for contact problems in multibody systems, the book describes the gross motion of multibody systems by using a two-dimensional formulation based on the absolute coordinates and employs different contact models to represent contact-impact events. Results for selected planar multibody mechanical systems are presented and utilized to discuss the main assumptions and procedures adopted throughout this work. The material provided here indicates that the prediction of the dynamic behavior of mechanical systems involving contact-impact strongly depends on the choice of contact force model. In short, the book provides a comprehensive resource for the multibody dynamics community and beyond on modeling contact forces and the dynamics of mechanical systems undergoing contact-impact events.
Mechanical engineering, an engineering discipline born of the needs of the industrial revolution, is once again asked to do its substantial share in the call for industrial renewal. The general call is urgent as we face profound issues of productivity and competitiveness that require engineering solu tions, among others. The Mechanical Engineering Series features graduate texts and research monographs intended to address the need for informa tion in contemporary areas of mechanical engineering. The series is conceived as a comprehensive one that will cover a broad range of concentrations important to mechanical engineering graduate edu cation and research. We are fortunate to have a distinguished roster of consulting editors, each an expert in one of the areas of concentration. The names of the consulting editors are listed on the front page of the volume. The areas of concentration are applied mechanics, biomechanics, computa tional mechanics, dynamic systems and control, energetics, mechanics of material, processing, thermal science, and tribology. Professor Leckie, the consulting editor for applied mechanics, and I are pleased to present this volume of the series: Kinematic and Dynamic Simulation of Multibody Systems: The Real-Time Challenge by Professors Garcia de Jal6n and Bayo. The selection of this volume underscores again the interest of the Mechanical Engineering Series to provide our readers with topical monographs as well as graduate texts. Austin Texas Frederick F. Ling v The first author dedicates this book to the memory of Prof F. Tegerizo (t 1988), who introduced him to kinematics.
