The Study on Simulation Schoolwork of Virtual Prototype for Corn Harvester
摘要
Abstract
In order to achieving working condition simulation and performance testing for corn harvester in virtual proto-type,the virtual simulation system was designed.Firstly,VR working condition environment was built,the terrain model and ground height model were achieved by digital function,and feature model was built by external reference,instantia-tion and bulletin board technology;Secondly,harvester operation model was achieved,the relationship between engine effective power and rotational velocity was linear,and the relationship between effective torque and rotational velocity was quadratic relationship.The steering control model and braking model was achieved;Mechanisms of corn harvester achieved relative motion by ODE physical engine,and then the interactive system for harvester model and VR working condition model was built;In the end,the test in virtual prototype for harvester was taken to guide the improvement of harvester design.关键词
