This monograph develops a unified methodology for dynamic analysis and minimization of the inertia-induced forces occurring in high speed multiloop planar as well as spatial mechanisms based on the multibody system modeling approach.

This book has evolved from the passionate desire of the authors in using the modern concepts of multibody dynamics for the design improvement of the machineries used in the rural sectors of India and The World. In this connection, the first author took up his doctoral research in 2003 whose findings have resulted in this book. It is expected that such developments will lead to a new research direction MuDRA, an acronym given by the authors to Multibody Dynamics for Rural Applications. The way Mu- DRA is pronounced it means 'money' in many Indian languages. It is hoped that practicing MuDRA will save or generate money for the rural people either by saving energy consumption of their machines or making their products cheaper to manufacture, hence, generating more money for their livelihood. In this book, the initial focus was to improve the dynamic behavior of carpet scrapping machines used to wash newly woven hand-knotted c- pets of India. However, the concepts and methodologies presented in the book are equally applicable to non-rural machineries, be they robots or - tomobiles or something else. The dynamic modeling used in this book to compute the inertia-induced and constraint forces for the carpet scrapping machine is based on the concept of the decoupled natural orthogonal c- plement (DeNOC) matrices. The concept is originally proposed by the second author for the dynamics modeling and simulation of serial and - rallel-type multibody systems, e. g.

Dr. Himanshu Chaudhary is Professor in Mechanical Engineering at Malaviya National Institute of Technology Jaipur (Rajasthan, India), where he has been teaching computer aided design, theory of machines and mechanisms, optimization methods for engineering design, and machine design. He received his B.E. from Rajasthan Technical University Kota (erstwhile Engineering College Kota) and M.Tech. from Indian Institute of Technology (IIT) Kanpur, both in mechanical engineering. He received his Ph.D. from Indian Institute of Technology (IIT) Delhi in 2007. His research interests include multibody system dynamics, dynamic balancing, and optimization of machines and mechanisms, including robotic systems. He has about 100 journal and conference publications to his credit. Springer Verlag published his book "Dynamics and Balancing of Multibody Systems" under series Lecture Notes in Applied and Computational Mechanics, Vol. 37, ISBN 978-3-540-78178-3, 2009. Prof. Subir Kumar Saha received his B.E. (NIT Durgapur) and M. Tech (IIT Kharagpur) in India, and Ph.D. from McGill University, Canada. Later, he joined Toshiba Corporation's R&D Center in Japan. In 1996, he joined IIT Delhi. As recognition of his international contributions, Prof. Saha was awarded the Humboldt Fellowship in 1999 by the AvH Foundation, Germany, and the Naren Gupta Chair Professorship at IIT Delhi in 2010. Presently, he is Project Director of IHFC (Technology Innovation Hub of IIT Delhi). Prof. Saha has authored several books, including a textbook on "Introduction to Robotics." To make robotics learning fun, a software RoboAnalyzer was developed under his supervision, and commercialized in 2022. He has more than 200 research publications and delivered several invited/keynote lectures in India and abroad. Prof. Vinay Gupta earned his Ph.D. from IIT Delhi in "Dynamic Model Based Optimum Design of Robotic Systems" from the Mechanical Engineering Department. He has two decades of teaching and research experience. He has led several projects as Principal Investigator in collaboration with the Rural Technology Action Group (RuTAG) at IIT Delhi. Prof. Gupta co-supervised a Ph.D. candidate at IIT Delhi, focusing on technology selection, analysis, and design for rural and economically weaker sections. His research interests include multibody dynamics, mechanisms, optimum design, and robotics.
