Modeling and Simulation of Hydraulic Systems by Bond Graphs

چکیده
This paper describes a unified approach to modeling and simulation of hydraulic systems using bond graphs. Unlike the others, the causalities are not applied in bond graph settings. This leads that mathematical model is generated in the form of differential algebraic equation (DAEs) and solved as such by suitable solver. Bond graph model of simple hydraulic system has developed using program BondSim. Several hydraulic components are developed and stored in the program library. They can be reused in modeling of complex systems. Simulation results are compared with ones obtained using MATLAB/Simulink showing good agreement. Proposed methodology can be applied to modeling of systems, which are composed of hydraulic, mechanical and electrical systems. This synergy is widely applied in field of mobile machines, machine tools and other industrial machines and devices where hydraulic systems are often used for power transmission. Bond graphs can be efficiency used in modeling of mechatronics system in whole.

In this paper, a new bond-graph library is introduced, programmed as part of the Dymola object-oriented graphical modeling environment. It is shown that the embedding of bond graphs into the Dymola modeling framework adds both expression power and flexibility to the bond-graph modeling methodology. The Dymola modeling framework is summarized, and the new bond-graph library is introduced. An (ac...
متن کاملResearch Note: Modeling and Simulation of Digital Systems Using Bond Graphs
Bond graphs are suitable tools for modeling many types of dynamical systems and can model these systems consisting of mechanical, electrical, fluidic, and pneumatic sub-systems. The advantage of a bond graph is that it can model non-linear systems and combinational systems. In this paper, the authors utilize bond graphs for modeling mechatronics systems. Mechatronics systems consist of mechanic...
