Study on virtual experiment methods of agricultural equipment based on Vega Prime

The design and development process of virtual experiment was analyzed in this paper. Then a virtual experiment system for agricultural equipment was founded by using MultiGen Creator, Vega Prime software and VC++ programming language. The system running process was introduced, together with tractor 3D modeling, operation data acquisition, dynamic modeling and drive, and collision detection. Furthermore, visual drive, synchronous display, tractor dynamics solution in network and other key techniques related to virtual experiment were discussed as well. The system provides a new method to tractor performance experiment, and the experimental results show stable operation of the system with the reliability and validity.
