摘　　要：针对9GSCC-1.4型水草收割机明轮装置的使用性能要求,运用惩罚函数法优化明轮的结构尺寸。根据优化的结构参数,基于Pro/E软件建立与物理样机相同的数字化模型,利用Pro/E的机构模块模拟真实状态下明轮装置的运转状况,对其进行干涉检验;利用Pro/MECHANICA模块对明轮部件的支撑架等机构进行强度分析;采用Pro/MECHANICA模块中的梁单元对明轮支撑架等构件理想化,在给定变化范围内为模型寻求满足应力要求的结构尺寸,完成了明轮装置的数字化设计,并实现了对系列化产品的动力学计算。According to property requirement of paddle wheel of 9GSCC-1.4 hydrophytes Harvester, structure dimension of paddle wheel was optimized with generalized penalty functions. Based on optimized structure parameters, digital model of physical sample machine was established with Pro/E, actual operation status of paddle wheel was simulated with Pro/ MECHANISM module, interference condition was tested, strength analyses for supporting structure of paddle wheel was carried out with Pro/MECHANICA module, and supporting structure was idealized with analytical beam cell of Pro/MECHANICA module, as a result, the best structure parameters which satisfied stress requirement of model were obtained in the given limit range, digital design process and dynamics count of paddle wheel were realized.
