Research of the Wheat Modeling Problems Based on Creator

Abstract

In order to making the virtual experiment results close to or equivalent to the real environmental effects, in addition to model realistic scenes, also need more accurate dynamic model. In this paper, based on research of hydraulic steering paddy and wheat combine harvester, first, used three-dimensional geometric model transformation technology to convert Pro/E model to a identified geometric model in VP virtual reality systems, second, used classical dynamics equations to build the mathematical model of this vehicle dynamics, finally, used VC++ programs to connect this two models, constructed a behavioral model of complete physics properties. This behavior model is not only more realistic than the geometry model in motion, but also it follows the laws of physics movement. It can effectively strengthen the authenticity of virtual experiment, provide an important platform to start agricultural machinery virtual characteristics test, and this Modeling Method can provide a reference for other agricultural machinery virtual reality platform to build.
