【Abstract】 The paper summarizes some kind of modeling methods studied by international efforts, which can realize automatic transformation from physical model to mathematical descriptions. These modeling methods are bond graph, object-oriented, block diagram, system graph and hybrid Petri net. The paper analyzes the software Schemebuilder developed by Engineering Design Center of Lancaster University,which is a modeling and simulation software for computer aided conceptual design of mechatronic system. Besides, the other softwares for mechatronic modeling and simulation suchas 20-sim basedon bondd graph method, and Dymola based on object-oriented method, then the software Matlab for simulation of control system and the software Adams for Mechanism system modeling and simulation are studied. In conclusion, the authors believe that the future of modeling and simulation software for mecha-tronic system is a software combined mechanism and control system together.更多还原
