Abstract


With institutions to speed, heavy , light -oriented development , institutional system functions increasingly depends on the merits of body system dynamics . Therefore, for the analysis of system dynamics at the institutional , bond graph method is difficult to implement complex system modeling agency problem , we propose a mechanism based on bond graph equivalent kinetic analysis . This paper proposes a dedicated system for complex areas of institutional dynamics modeling. To do this , first summarizes the mechanical dynamics analysis methods generally bond graph modeling history and research status , elaborated bond graph modeling the basic theory . Through an integrated graph modeling together with many of the key literature data obtained only due to the general scalar bond graph concept , you can not implement complex system of institutions and space agencies system modeling , and vector bond graph instead of using the expression vector scalar expression You can make general bond graph modeling deficiencies. Since the bond graph models and physical models in the structure has a corresponding relationship for complex mechanical systems , vector bond graph modeling can be achieved , but the resulting models are more complex and difficult to simulation analysis . In order to make the bond graph method is more simple to implement complex system of institutions and space agencies planar system modeling , this is equivalent to the classical kinetic analysis method to improve, and the bond graph method combined with the complex plane body system this paper presents the general bond graph based institution equivalent kinetic analysis ; and on this basis , the space agencies for complex systems , and further proposed based vector bond graph equivalent kinetic analysis of institutions to achieve a simple and rapid prototyping . This paper uses this method to implement a large-scale forging manipulator dynamics modeling clamping mechanism for clamping the dynamics of transient simulation analysis , simulation results show that the established system dynamics model is correct and effective , and the traditional dynamic analysis methods, models are correct and more concise , which will promote the application of bond graphs to complex multi-body system modeling domain, as bond graph laid the foundation for further research .
