Optimal Design of Complex Mechanical Systems

This book presents foundations and practical application of multi-objective optimization methods to Vehicle Design Problems, bolstered with an extensive collection of examples. Opening with a broad theoretical introduction to the optimization of complex mechanical systems and multi-objective optimization methods, the book presents several applications which are extensively exposed here for the first time. The book includes examples of proposed methods to the solution of real vehicle design problems.The book is devoted both to researchers wishing to acquire a basic knowledge on the optimization of complex mechanical systems and to engineers specialist in the field of vehicle design. §In the introductory chapter, the main optimization problems issues are briefly presented without resorting to involved mathematics. Therefore the reader is aware of what is actually the optimization of complex systems and the actual problem solving capabilities available. All of these topics are dealt with in a complete mathematical form in the second part of the book.§In the third part of the book, a number of relevant optimization problems referring to ground vehicles are solved, whenever possible, in analytical form. The best compromise between handling, road holding and comfort of road vehicles is studied using validated full non linear models. The optimal design of railway vehicles is dealt with. Additionally the design of springs and other vehicle sub-systems are reinterpreted making use of the presented optimization theories and may bring new ideas for future applications.§Though the optimization of complex mechanical systems will be continuously updated in the near future, the book will remain informative both with reference to theory presented, and with reference to those optimization examples which pertain to engineering science. §Giampiero Mastinu, Ph.D., professor of Vehicle System Engineering at the Politecnico di Milano (Technical University), Italy§Massimiliano Gobbi, Ph.D., professor of Optimal Design at the Politecnico di Milano (Technical University), Italy§Carlo Miano, Ph.D., research engineer at the Ferrari Formula 1 Team, Maranello (Modena) Italy
