Aiming at the electronic equipment simulator, the mechanism modeling method is researched. The main modeling methods are summarized. The electronic equipment mechanism model based on signal flow is proposed according to the modular modeling theory, which includes four steps： equipment decomposition, signal flow chart extraction, sub-model establishment and complete model establishment. The modeling process is introduced. The sub-models and the structure of the complete model are introduced emphatically. The muhi- resolution modeling （MRM） and time management mechanism of the model are discussed. The application of this new method in the fault modeling is analyzed. A mechanism modeling system with 3-level- resolution is put forward. The innovations include： the method is compatible with other modeling methods by adjusting the resolution, and it is an ution to the problem of fault equipment modeling can be solved effectively. Analysis result shows that proposed method can meet the demands of mechanism model for simulators at different levels.
