Stress Concentration impact under Thermal and Dynamic Loads and Techniques of Reconfigurable Manufacturing

Abstract

Geometric discontinuities cause a substantial variety of stress and create a huge increment in stress. The high worry because of the variety of geometry is called as 'stress focus'. This will increment when the heaps are encourage connected. There are numerous examiners who have contemplated the anxiety circulation around the scores, grooves, also, different anomalies of different machine parts. This paper examinations the impacts of warm and weariness stack on a steam turbine rotor under the working conditions. Worries because of warm and element heaps of High Pressure Steam Turbine Rotor of 210MW power station are found in two phases. A source code is created for figuring the ostensible worry at every area of HPT rotor. Most extreme anxiety is acquired utilizing FEA at the relating area. Warm and Fatigue Stress Concentration Factors at every area are computed. It is watched that the SCF because of the joined impact of warm and element loads at the temperatures past 5400 C is surpassing the safe limits.
