摘要
介绍了另一种水轮机金属蜗壳重量计算方法。通过对三维图形的分析,采用类似放样展开法,计算蜗壳分段件几何面积,从而得出蜗壳各段重量值。
This paper introduces a method for calculating the weight of metal spiral case for turbine.By this method,the weight of each spiral case section is calculated according to the geometric area of each section which obtains from the analysis of three-dimensional graphics and the lofting expansion.
