汽轮机间隙气流激振力分析及计算程序设计

Analysis of the Air--Exciting--Vibration Force of the Steam Turbine and its Computer Program Designing

本文给出了基于流体动力学的计算汽轮机均匀气流场和非均匀气流场直叶片、短扭叶片、长扭叶片以及汽轮机调节级间隙气流激振力的计算公式 ,介绍了基于以上公式的汽轮机间隙气流激振力计算程序 ,并讨论了程序设计中有关积分的处理方法。

Based on the hydro--dynamics,computing formulas of air-exciting-vibration are presented for the straight, short twist and long twist blades and the control stages of the steam turbine in the uniform and non-uniform air-flow fields. Furthermore introduced are computing program designing for the air-exciting-vibration force and methods for the intepration in the formulas.\;
