Aiming at the problem of multibody system difficult expression using bond graph, Chapter four systemically promotes the bond graph expression methods of complex mechanical system based on Euler equation of Newtonian mechanics, Lagrange equations of the first kind and Lagrange equations of the second kind.
By establishing the bond graph of city bus's power transmission and using the Matlab/Simulink based on the bond graph, this dissertation established the simulation model of braking performance of electromagnetic brake. Through simulating the braking performance of DHZ100, the influence of this brake on city bus had been obtained.
The software can automatically deducate the character state equation from the power bond graph input by user,then put the result and parameters input by user into the ODE file which is required by MATLAB. MATLAB can solve the ODE file with numerical solution method of ordinary differential equation.
Based on graph and object-oriented technique, the dissertation establishes a visual modeling environment. It remedies the shortcomings of hydraulic simulation software based on Power Bond Graph in the foreside model input and treatment by introducing the modeling style of hydraulic principle figure andgraphical power bond graph.
An algorithm is presented for constructing linear graph and bond graph representations of chemical reaction systems.
Driven by space mapping among function and structure, the feature model and its parameters are restricted with the bond graph represented simulation model, which is constructed with functional components in simulation library at the system-level.
The models of the vascular system and the ventricular activity have been developed using the Bond Graph formalism, as it proposes a unified representation for all energetic domains, facilitating the integration of mechanic and hydraulic phenomena.
It is demonstrated that the characteristic polynomial of the adjacency matrix of the PPP bond graph is invariant in every SCF iteration.
In this paper, three different unified modelling strategies, based on the virtual work principle, linear graph and bond graph theories, are presented and compared.
A new representation calledbehavior graphs (derived from bond graphs) has been developed to facilitate behavioral reasoning.
The dynamic systems are modeled using bond graphs.
Bond graphs provide a unified approach to the analysis, synthesis and evaluation of dynamic engineering systems.
Though the scope of this investigation is limited to systems represented by bond graphs, the domain is wide enough to include many interesting applications like pump systems and vibration isolation systems.
In particular, we report on our experience using switched bond graphs for the modelling of hardware components in hybrid systems.
