Bond Graph Theory

A half-car vibration model of an electric vehicle driven by rear in-wheel motors was developed using bond graph theory and the modular modeling method. Based on the bond graph model, modal analysis was carried out to study the vibration characteristics of the electric vehicle. To verify the effectiveness of the established model, the results were compared to ones computed on the ground of modal analysis and Newton equations. The comparison shows that the vibration model of the electric vehicle based on bond graph theory not only is able to better compute the natural frequency but also can easily determine the deformation mode, momentum mode, and other isomorphism modes and describe the dynamic characteristics of an electric vehicle driven by in-wheel motors more comprehensively than other modal analysis methods.

Simulation Results

The power bond graph of hydraulic system of power-slipway for combined machine tools was built on the basis of analysis on its hydraulic system and actual working cases. Dynamic model of hydraulic system of power-slipway was built. At the same time, making use of Simulink, dynamic simulation of hydraulic system of power-slipway was carried out. Influence law of primary technology parameters on dynamic characteristics of the hydraulic system of power-slipway was expounded. The simulation results will provide theory basis for performance analysis and optimal design of hydraulic system of power-slipway for combined machine tools.

Bond Graph Theory

Based on the bond graph theory, the acquisition of state equation of vehicle suspension is presented. Set an example to a five degrees of freedom vehicle suspension model ,the simulated results are obtained with the aid of Matlab/Simulink software. Bond graphs are equation based , and are superior to traditional differential equations, they can provide the dynamic digital simulation in time and frequency domain, they can present the static simulation and omit the transition and class-decreasing process which is needed for traditional differential equations.
