Numerical Simulation of Mechatronic Sensors and Actuators

The focus of this book is the physical modeling of mechatronic sensors and actuators and their precise numerical simulation using the Finite Element Method (FEM). It is complete in the sense that it discusses the physical modeling as well as numerical computation. In addition, a comprehensive introduction to finite elements, including their computer implementation, is given. Furthermore, industrial applications motivates the reader with clear demonstrations the importance of numerical simulation for industry. A large part of the book describes the application of the developed numerical calculation schemes to industrial problems, e.g.: analysis and optimiztion of electrodynamic loudspeakers; acoustic emission of electric power transformers; and ultrasonic imaging system based on electrostatic micromachined transducers.

Deals with CAE of Sensors and Actuators and modern tools for the numerical simulation of Electromechanical Transducers Provides a comprehensive understanding of the main phenomena related to coupled fields of different physical origin (multifield problems) Based on graduate courses at the University Erlangen-Nürnberg Includes supplementary material: sn.pub/extras

Klappentext

The second edition of this book fully preserves the character of the first edition to combine the detailed physical modeling of mechatronic systems and their precise numerical simulation using the Finite Element (FE) method. Most of the text and general appearance of the previous edition were retained, while the coverage was extended and the presentation improved.

In this second edition, the author enhances and improves many discussions on principles and methods. For example, he included a discussion of a priori estimates as well as a new section discussing locking effects as occurring in the numerical computation of thin mechanical structures. He also deepens the discussion of the physics of sound generation and propagation as well as includes the case of flow induced sound.

A large part of the book describes the application of the developed numerical calculation schemes to industrial problems, e.g.: analysis and optimization of electrodynamic loudspeakers. In these parts, new computational methods are included, and last but not least, this new edition contains a new chapter on computational aeroacoustics to study the complex phenomenon of flow induced noise.
