steamtight

1. The calculations of the strength,stiffness and steamtight are very importang when high pressure and intermediate pressure casing of 300 MW steam turbine are designed.

本文采用三维弹性接触理论,建立300MW汽轮机高中压外缸的有限元模型,进而计算了汽缸的温度场、应力和变形。

2. Preliminary Discussion on Increasing Steamtight Degree of Steam Engines
