2024.3-present: Emeritus Professor, Department of Mechatronics Engineering, Chungnam National University, Korea 1993.3-2023.2: Professor, Department of Mechatronics Engineering, Chungnam National University, Korea 1989.8-1993.2: Adjunct Professor, Department of Mechanical Engineering, University of Iowa, U.S.A. 1988.8-1993.2: Associate researcher, Center for Computer Aided Design, University of Iowa, U.S.A. Abstract
Multibody system dynamics is a branch of computational mechanics, especially the study of the dynamic behavior of interconnected rigid or flexible bodies. Different from the structural dynamics, each body can undergo large translational and rotational motion. With the advent of the modern computer in the middle of 1960, multibody system dynamics started to grow from simple problems consisting of a few bodies to complicated applications with millions of bodies today. Since the multibody system dynamics stems from computation dynamics, modeling and formalisms are the key ingredients with their solution method such as DAE (Differential Algebraic Equations) solvers. Then, multibody system dynamics has been explored in many different areas, such as flexible multibody dynamics, contact mechanics, bio-mechanics, vehicle dynamics, robotics and mechatronics, real-time dynamics applications, and many-body dynamics with GPU for multibody and fluid interactions. In order for the field of multibody system dynamics to continue to explore the direction of its development and to be sustainable, it is necessary to understand the history of multibody system dynamics and to gain a comprehension of the activities in the multibody system dynamics society. At the same time, multibody researchers take into consideration how their researches transfer to the education of the multibody system dynamics. This presentation will provide an overview of the history of multibody system dynamics in conjunction with computational dynamics and commercial software available these days. Also, the activities of the multibody system dynamics society will be discussed, based on the multibody dynamics conferences in which the lecturer has been involved for the past quarter century. |

Future Perspectives of Multibody System DynamicsAki Mikkola Biography
2002–present Professor of Virtual Design, Department of Mechanical Engineering, LUT University 2019–present Visiting Professor, Chongqing University 2000-2002 Visiting Scholar, University of Illinois at Chicago, Chicago, Illinois, USA, (2 years) 1998–2000 Adjunct Professor, Lappeenranta University of Technology, Lappeenranta, Finland Abstract
Traditionally used to enhance product development processes, multibody system dynamics is now being extended to cover the entire product lifecycle, improving insights into product usage, customer understanding, production, and service-based businesses. This extension is crucial as traditional material-based business processes are increasingly supplemented by models centered on data and knowledge processing. The study illustrates several applications, including multibody system dynamics in gamification, integration with real machines through reality-driven simulation where models are actuated by sensor signals, and the use of artificial intelligence to control models, generating data essential for further AI developments. It also explores biomechanical applications, enhancing understanding of human behavior on assembly lines. This presentation underscores that multibody system dynamics is becoming an indispensable tool across various product processes, signifying its expanding role beyond traditional applications. |

The Dynamics and Control of an Autonomous Bicycle SystemCaishan Liu Biography
2008-present, Professor, College of Engineering, Peking University 2005.8-2006.7 Visiting Scholar, Australian National University 2008.07-2008.09, Visiting Professor, INRIA Grenoble, France 2011.01-2011.04, Visting Professor, New Mexico State University Abstract
In this talk, we will introduce a theoretical framework for dynamics modeling and stability analysis of a controlled bicycle. Here, the control laws are served as servo-constraints imposed on the bicycle system, and the tools of geometric mechanics are used to reduce the dimensions of the dynamical equations. Based on the stability analysis, we unveil some important properties inherent in the autonomous bicycle system. Furthermore, we present some experimental results to verify the theoretical findings. |
