Abstract
Similar to other machinery products, numerous analysis and tests would consume large amount of manpower and resources before paddy machinery putting into the mass markets. A method to establish the Virtual Proving Ground (VPG) for paddy machinery is proposed. Parameters stored with model nodes are obtained by collision detection between machine and scene. Motion equations of transplanting mechanism are derived with some simple transformations referring to a rice transplanter. Then working process simulation of the rice transplanter in virtual reality environment is realized by calling functions encapsulated in Vega Prime in a VC++ environment. Moreover some solutions for researching virtual testing are proposed.
