The Enveloping Curve of Variale-Radius Cycle on the Curved Traverse and Its Application

本文提出了曲导线上变径圆包络线的概念,并推导出求解包络线的解析算式,给出了计算机实现的具体算法。通过离心泵叶轮轴面流道CAD等实例中的应用,证明该方法可作为基础算法应用到许多相关的领域中。

The concept of the enveloping curve of the variale-radius cycle on the curved traverse is proposed in this paper, and the analytical formula for the solution of the enveloping curve derived, with practical computing method given. Applications of this method on CAD for axial face flowing path of the impeller of the centrifugal pump has shown that it would find extent application in some other fields as a fundamental computing approach.
