In recent years,the demand for mechatronics products has changed dramatically,which will be oriented to control,electronics and machinery at the same time,which poses new challenges to product research and development capabilities.As a multi-domain digital model that can reflect the essential characteristics of products,virtual prototype technology can meet the requirements of refined technology and meet the complex and changeable realistic needs.Based on the analysis of mechatronics modeling needs and basic processes based on virtual prototype technology,this paper proposes mechatronics modeling through empirical analysis,to lay a good foundation for the scientific production of mechanical manufacturing.
