【摘要】 由于离心叶轮外形的复杂性,用传统的三维造型软件直接建模步骤非常繁琐,处理数量庞大的坐标点更是费时费力。通过对叶轮造型方法进行研究,提出了一种基于Bladegen的离心叶轮造型方法,避免了数据调入和数据处理的繁琐,根据计算得到的几何尺寸运用Bladegen生成叶片型线,再将生成的叶型数据文件导入Pro/E进行实体造型。将Bladegen运用到叶轮造型中可以快速生成满足相关条件的叶轮,同时以数据文件作为两个软件之间的桥梁方便了模型的修改,缩短了叶轮设计周期,节约了成本。更多还原

【Abstract】 The modeling procedure is very complicated with the traditional 3D modeling software due to the complexity of the shape of the centrifugal impeller. It’s more time-consuming and laborious processing the large number of data. Three dimensional modeling procedure based on Bladegen is introduced through the research of the centrifugal impeller. According to the geometric dimension obtained by calculation,the blade model lines that generated in Bladegen are imported in Pro/E to generate the impeller entity so as to avoid the complex step of importing data and processing data. Bladegen module used in impeller modeling can rapidly generate impellers that fulfill the relevant conditions and modify the model using data files as an intermediary,shorten the computation period and save the cost.更多还原
