【摘要】 以ＦＯＲＴＲＡＮ语言和ＡｕｔｏＣＡＤ图形软件作为ＣＡＤ系统的支撑环境，叶轮优化设计采用简化三元流动模型，环量沿径向分布可任意控制，优化参数可根据需要选取，叶片造型采用平面叶栅法。模型试验表明，设计点准确、设计质量高。并且在国内首次利用数控加工中心实现了泵转轮叶片ＣＡＭ。更多还原

【Abstract】 The CAD system based on FORTRAN and AutoCAD Optimal design of axial flow pump impellers based on simplified three dimensional flow model in which the velocity distribution within the flow range behind the blade can be optionally controlled and the blade is moulded by plane cascade mode CAM of the blade have be first realized domestically with a numerically controlled miller更多还原
