Paper Abstract

According to the tendency that hydraulic drive and control systems become more complex and require higher dynamic performance, an advanced visual modeling and simulation methodology for hydraulic systems was proposed. A bond graph was introduced as a modeling tool that provides an intuitive and unified approach to the modeling of multi-domain and nonlinear hydraulic systems. An open-ended hydraulic module library was established by uniting the theories of bond graph and modularization. The Hydraulic Visual Modeling and Simulation Platform (HVMSP) was compiled with the object-oriented VISUAL BASIC language. With the platform, the MATLAB language, which is well recognized as a powerful tool for matrix computation and dynamic simulation, can be background activated. After a series of relevant background computation process, the bond graph model can be automatically translated into a mathematical model, and the SIMULINK toolbox of MATLAB will simulate the mathematical model of hydraulic system. In the end, the feasibility and efficiency of the method are verified with a given practical example.
