摘　　要：取力器(Power Take Off,PTO)是水稻插秧机动力传递路线中的关键部件,为了探究PTO结构和工作原理,开展了基于三维扫描仪及Geomagic Design X的洋马VP-6D插秧机底盘PTO逆向建模研究,阐述了模型点云数据的获取与处理、模型的建立与误差分析、格式的转换及模型装配等方法,并对逆向模型进行了建模误差检测。检测结果表明,上下壳体建模偏差平均值分别为1.0565 mm和1.0325 mm,获得了精度较高的数字模型,可为PTO后续研究及优化设计提供参考。Power Take Off(PTO)is a key component in power transmission route of rice transplanter.In order to explore the structure and working principle of PTO,reverse modeling of PTO chassis of Yanmar VP-6D transplanter based on 3D scanner and Geomagic Design X was carried out.The methods of acquisition and processing of model point cloud data,model establishment and error analysis,format conversion and model assembly were elaborated.The modeling error detection of the reverse model is also carried out.The test results show that the average modeling deviation of upper and lower shells is 1.0565 mm and 1.0325 mm respectively,which provides a reference for PTO follow-up study and optimization design.
