The assembly simulation and the mechanism simulation of key parts of virtual prototyping of a small size sugarcane combine harvester were studied by virtual design. The simulation design method and key technology of virtual prototyping based on I DEAS were discussed. The mechanism simulation provided key point's forces, displacement, velocity, acceleration and kinematic interference check. In the virtual environment, the parameters and the mechanism were modified to be suited to the reality. Finally, the fittest velocity ratio of cut help device and other required movement parameters reality were obtained, and the animation process of device and graph result function of the simulation were also provided. This method could reduce the design cost and shorten developing time of product.
