This paper introduces a versatile simulation software of system's dynamic properties for power hand graph oriented-PBGSIM. This software was developed on the platform of MATLAB so as to give full play to the advantages of the power hand gash method in analyzing system's dynamic properties and be able to deal with complicated systems including of all kinds of loops. Starting from editting a system's bond graph model, the software can automatically distinguish errors and give prompts, create the system's mathematical mathematical model(both in symbolic and numeral formulas), calculate the simulation and output to cater for user's requirements. Users can conveniently modify elements' parameters or the model until attaining a satisfying output. It can also optimize the system's parameters for its dynamic properties, after given optimizing varieties. The achievement of researching this software provides a new approach to simulation models by power bond graph and an available tool for complicated system's dynamic design and optimization.
