农田喷灌车虚拟仿真设计

Virtual Simulation Design for Agricultural Spraying Machinery

选取农田喷灌车为研究对象,使用Pro/E对喷灌车进行机械三维基础建模,利用3ds Max对模型进行后期处理,包括模型顶点和面的处理、添加材质、机具命名、轴心调整等。在Unity3D建立虚拟场景,对喷灌车的各个部件按照仿真需要进行父子关系的处理,并建立辅助仿真对象。通过分析喷灌车运动原理,建立相应的数学模型,并在此基础上对喷灌车的行驶与机械臂的展开与折叠进行虚拟仿真。通过对利用父子关系加旋转运动的有机结合,实现了农机复杂运动仿真的通用方法,可以推广到各种农机具的虚拟仿真展示中。

Select agricultural spraying machine for the study , using Pro/E on mechanical modelingthe for the basis of three-dimensional spraying machine ,using 3ds Max model post-processing, including models of vertices and faces ,and adding materials,equipment named,axis adjustmented and so on.Built on the Unity3D virtual scene,each part of the spraying machine needs to be processed in accordance with the simulation and the establishment of paternity assisted simulation object.By analyzing the spraying machine movement principle ,establish the appropriate mathematical model , and on this basis ,the spraying machine with manipulator expand and collapse with virtual simulation .Through the use of parent-child relationships and rotation movements combine achieve the common agricultural complex motion simulation , the method can be extended to a variety of farm machinery virtual simulation show .
