Under act of the alternating thermalstress, thermalfatigue is one of theprimary invalidity forms of cast iron workpiece.
在热交变应力的作用下,热疲劳是铸铁工件的主要失效形式之一。

The design mainly involves the analysis of the stress, fatigue, thermal ratchet and fracture mechanics, the analysis of flow-induced vibration of the internals and the test verification.
Equipment life-span diagnoses mainly research the variation rules of unit part in unsteady temperature and thermalstress, fatigue characteristic of metals and life deterioration of equipments.
