First of all, the field of mechatronics incorporates very different domains and similarly varied methods of description The field of electronics includes analogue and digital, as well as continuous and event-oriented, processes The same is true of mechanics, although often... fine and available symmetries are exploited 2.4.3 Physical modelling Introduction In physical modelling the laws of physics are used to describe the behaviour and inner action mechanism of a system or a component The selection of the relevant relationships depending upon suitability and efficiency and the establishment of cause and effect chains, requires a comprehensive understanding of the system and. .. computer The latter is called simulation and permits the processing of significantly greater data quantities, and thus the consideration of significantly more complex problems The development of models for simulation is a difficult process, and thus prone to errors On the other hand, the reliability of a simulation is crucially dependent upon the quality of the model So methods and tools are required that... normally 2 PRINCIPLES OF MODELLING AND SIMULATION 14 displayed in a debugger that shows the current status of the software, i.e program line and variable values, plus their outputs on the terminal Without this type of simulation, software development would be unthinkable Like electronics, the construction of mechanical systems in reality is very expensive in terms of time and costs In many of the industries... the former case we speak of mechatronics, in the latter of micromechatronics or microelectromechanical systems (MEMS) As was discovered during the course of this project, although the dimensions of the mechanics in the systems under investigation may vary, the methods used for modelling and simulation are largely the same, which makes the joint consideration of macromechanics and micromechanics an obvious... allowed modelling and simulation to penetrate the majority of engineering disciplines and natural and social sciences Regardless of whether the matter under debate is the design of wheel suspension for a car, the metabolism of a bacteria, or the introduction of a new interest formula, models of these real systems are always drawn upon to gain an understanding of the inner relationships of the system and .
