摘要: 采用Unity3D研发了一套林木联合采育机虚拟训练系统。以某型林木联合采育机为原型,采用SolidWorks辅助3dsMAX进行精细建模,将三维模型导入Unity3D中,搭建虚拟作业场景,对林木联合采育机的各个部件按照仿真需要进行父子关系的处理,通过分析机械臂运动原理,建立相应的数学模型,实现机械臂的运动仿真,通过基于碰撞点和刀锯形成平面的切割算法来实现对树木的切割模拟。实验结果表明:系统实现了林木联合采育机的虚拟采伐作业,沉浸感强,交互效果好,可满足林木联合采育机操作人员的训练需求。

Abstract: A forestry felling & cultivation machine virtual training system based on Unity3D was developed. The models of forestry felling & cultivation machine were built up using 3dsMAX with the assistance of SolidWorks based on a forestry felling & cultivation machine. The models of forestry felling & cultivation machine and trees were imported into Unity3D to create a virtual operating environment. Each part of forestry felling & cultivation machine needs to be processed for the establishment of paternity in accordance with the simulation, the corresponding mathematical model was established to simulate the motion of the manipulator based on the analysis of the motion principle of the manipulator. It realized the cutting on tree’s model through a cutting algorithm which created a plane formed by the collision points and the saws. The test results show that the virtual logging of forestry felling & cultivation machine is realized, and the system can meet the training needs of forestry felling & cultivation machine operator with strong sense of immersion and good interaction.

Key words: forestry felling & cultivation machine, virtual reality, unity3d, virtual cutting
