锅炉受压元件疲劳强度计算

Fatigue Strength Calculations of the Boiler Pressure Elements.

由于锅炉受压元件在服役过程中不可避免地要经受交变应力的作用,设计时应考虑疲劳问题,本文介绍了疲劳强度计算的步骤、方法,并进行了讨论与分析。

Since the pressure elements of boiler in service are inevitably subjectd to the action of alternate stresses, the fatigue problem should be considered in design. This paper introduces the procedures and methods of the fatigue strength calculations.
