Opis

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."

Recenzje

From the reviews:

"This is a monograph describing applications of multibody dynamic analysis methods with specific physical systems. The focus is upon the development of dynamics formulations convenient for machine design. ... The book is well-written with high-quality graphics and printing. ... The book will thus probably be of greatest interest and use to engineers and researchers who are wanting to transfer multibody dynamics theories into design application." (Roland L. Huston, Zentrablatt MATH, Vol. 1153, 2009)

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. Dynamic analysis is prerequisite for the dynamic balancing of mechanisms. The balancing of mechanisms is one of the crucial steps in design of high speed machinery and is a difficult one due to trade-off amongst various dynamic quantities, e.g., shaking force, shaking moment, bearing reactions, and driving torques/forces. Hence, it is essentially an optimization problem where various dynamic quantities are computed repeatedly.
