The design and development of multidisciplinary systems requires a unified way and simulating integration that can nearly adapts to every energy domain.An approach of generating behaviour equations for deferent fields,and entirely solving simulating integration of multidisciplinary systems is presented,including the multibody motion and dynamic analyse of mechanic.The final differential-algebraic equations(DAEs) will be solved with numerical methods that generate approximate solution.Based on the linear graph theory and combined with the module in the software engineering,EELG(Extensible Elementary Linear Graph)technique was proposed that could be applied to multidisciplinary systems,encapsulated linear graph into the elementary graph,and made the element module with the hierarchy,reusing and extensibility.Finally,with the EELG method,the Modelica of Object Oriented modeling language was adopted to develop the module library,and the Dymola software platform was implemented on.The approach is proved by the correct result.
