Abstract: To make the Virtual Prototyping (VP) of complex mechatronic system replace the physical prototyping and to improve the quality and efficiency of complex mechatronic product design,the development and application of VP depends on advancement of its key supporting technologies were elaborated.The advancement and existing problems of several key supporting techniques were discussed,which included VP definition,modeling,multi-domain simulation,Multi-disciplinary Design Optimization(MDO),methodology of system integration and model management.The technology and the direction for VP of complex mechatronic system were given,which laid research foundation for VP design of complex mechatronic system.

Key words: virtual prototyping, multi-domain simulation, collaborative modeling, multi-disciplinary design optimization, system integration, model management
