摘要
为了克服传统谷物联合收获机实验易受环境影响、周期长、成本高、危险性大等问题,运用三维虚拟仿真技术创建了谷物联合收获机虚拟仿真实验教学平台。该平台包含联合收获机整机及关键装置结构与工作原理主动认知系统,以及往复式切割器和切流式脱粒辊筒性能实验模块,通过8个核心知识点的实验设计,系统探究关键参数对收获性能的影响规律与作用机理。教学实践表明,该实验能有效提升学生对谷物收获环节重点、难点内容的理解和掌握,为复杂工程问题探究分析能力和实践创新能力培养开辟了新的教学路径。
Traditional harvesting experiment of grain combiner faces on problems of environmental fragile,time-consuming,high cost and danger.To overcome these problems,this paper established the 3D simulation teaching platform for combine harvester based on virtual simulation technology.This experiment teaching platform is composed of the whole combine harvester and the active cognitive system of combine harvester and its key mechanisms,the performance experiment module of reciprocating cutter and tangential flow threshing cylinder.With experiments of eight knowledge points,the influence law and mechanism of key parameters on harvesting performance are deeply explored.The application of this experiment teaching platform shows that it effectively improves the comprehension and master of students on key and difficult knowledge points in the class,and opens up a new teaching path to cultivate students’ability of solving complex problems and practical innovation.
