摘要
应用有限元软件ANSYS对超超临界汽轮机主汽调节阀进行瞬态过盈接触分析、热固耦合分析,给出了主蒸汽温度的下降速度和过盈量之间的影响关系。为进一步研究提高阀门效率和结构改进提供参考。
This article introduces ultra supercritical turbine valve contact analysis of transient interference,thermal-solid coupling analysis with ANSYS analysis software.The relation of MST decreasing rate and the shrinkage fitness are presented.The article provides the reference for further research of increasing of MSV efficiency and structural development in main valve.
