摘　　要：为改善传统设计方法中存在的零件设计配合契合度较差的问题,基于虚拟现实技术进行了通用型农业零部件设计。首先,进行零部件的二维平面草图绘制,按照实际比例设置零部件三维结构,并将设计好的三维结构进行装配组合,调整相互嵌入位置的尺寸;然后,采用平衡系数和动态模拟演示的方式进行模型组调整和公差优化,实现基于虚拟现实的农业零部件设计。实验数据表明:与传统零部件设计方法相比,虚拟现实设计方法可以将零部件契合度提高约17%,能够满足农业零部件设计的精度需求。In order to improve the poor fit of parts design in traditional design methods,this paper designs general agricultural parts based on virtual reality technology.In the design process,firstly,the two-dimensional plane sketch of the parts is drawn,and the three-dimensional structure of the parts is set according to the actual scale,and the designed three-dimensional structure is assembled to adjust the size of the mutual embedded position.At the same time,the balance coefficient and dynamic simulation demonstration are used to adjust the model group and optimize the tolerance,so as to realize the design of agricultural parts based on virtual reality.The experimental data show that,compared with the traditional parts design method,the virtual reality design method can improve the fitting degree of parts by about 17%,which indicates that the virtual reality parts design method can meet the accuracy requirements of agricultural parts design.
