Integrated Design Of Mechatronic Products Based On The Generalized Bond Graph Method,

Mechatronics design requires that a mechanical system and an electronical system be designed as an integrated system. This paper starts with an overview of the methods and tools for modelling and simulation of mechatronics systems, with parameters that are directly related to the real-world system. Common block-diagram or equation-based simulation packages can hardly support some features of mechatronics. This paper explores a new design method which can effectively solve the problem. The energy-based approach towards modelling of physical systems allows the construction of resuable and easily extendible models.One of the main and most challenging steps in the design and analysis of a mechatronics system is to generate a computer model. This paper explores the generalized bond graph technique as a modelling tool to generate a typical mechatronic model. It deduce many subjects' physical elements into several bond graph elements by means of energy flow, further synthesize these bond graph elements we can gain generalized bond graph elements which is less than before. Connect these generalized bond graph elements into an integal model by special rule, can form any interdisciplinary models. The theory will be illustrated with an example of typical mechatronics system - a mobile robot. Several aspects of mobile robot design have been investigated in order to show that the generalized bond graph modeling technique can help users in the process of creating mechatronics systems.Now, several tools are already available but there are still substantial shortcomings. The paper gives prospects about the developments needed to come to better design tools in the future. With the aid of modelling and simulation software 20-sim3.6, the established mechatronics model can be checked easily and exactly. This paper manages to output many simulation outcomes of the behaviors of the mobile robot. We manage to make high level input of models in many forms including generalized bond graphs and supports efficient symbolic and numerical analysis as well as simulation and visualization to be real. Much more important, with fewer jobs, we can obtain equations of the mechatronics system. Real mechatronic design, involving input from specialists from varying disciplines, requires that the system can be represented in multiple views. So, an automated performance assessment of mechatronic motion systems during the conceptual design stage is discussed.
