Beschreibung
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. 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; acoustic emission of electric power transformers; dynamic analysis of electromagnetic valves; piezoelectric stack actuators such as used in common-rail diesel injection systems; and capacitive micromachined ultrasound transducers. These applications clearly demonstrate the importance of numerical simulation within the design process of mechatronic sensors and actuators.
The focus of this book is concerned with the modeling and precise numerical simulation of mechatronic sensors and actuators. These sensors, actuators, and sensor - actuator systems are based on the mutual interaction of the me chanical field with a magnetic, an electrostatic or an electromagnetic field. In many cases the transducer is immersed in an acoustic fluid and the solid-fluid coupling has to be taken into account. Examples are: piezoelectric stack ac tuators for common-rail injection systems, micromachined electrostatic gyro sensors used in stabilizing systems of automobiles or ultrasonic imaging sys tems for medical diagnostics. The modeling of mechatronic sensors and actuators leads to so-called mul tifield problems, which are described by a system of nonlinear partial dif ferential equations. Such systems can not be solved analytically and, thus a numerical calculation scheme has to be applied. The schemes discussed in this book are based on the finite element (FE) method, which is capable of efficiently solving the partial differential equations. The complexity of the simulation of multifield problems consists in the simultaneous computation of the involved single fields as well as in the coupling terms, which intro duce additional nonlinearities. Examples are: moving conductive (electrically charged) body within a magnetic (an electric) field, electromagnetic and/or electrostatic forces.
