Vibration Response of Steam Turbine Healthy and Cracked Blade under the Stress Stiffening and Spin Softening Effects
Autor: Rajesh K Bhamu, Aakash Shukla, Satish C Sharma, S P Harsha
Publikováno v: Proceedings of the Institution of Mechanical Engineers, Part K: Journal of Multi-body Dynamics. 236:224-243
In the present paper, vibration responses of the healthy and cracked blade under the influence of stress-stiffening and spin-softening have been studied. The three-dimensional finite element-based numerical analysis is carried out to study the blade'

Performance Analysis of Laminated Rubber Base Isolator-Based Secondary Suspensions under Deflated Air-Spring
Autor: Vikas Tiwari, Satish C. Sharma, S. P. Harsha
Publikováno v: International Journal of Structural Stability and Dynamics.
In a railroad wagon, the vertical excitation on the wheels originated from the track irregularities; the air spring model is reliably used to restrict these abnormal vibrations at a required level and improve traveler comfort. When air springs deflat

Low-Cycle Fatigue Life Prediction of LP Steam Turbine Blade for Various Blade–Rotor Fixity Conditions
Autor: Rajesh K. Bhamu, Satish C. Sharma, Akash Shukla, S. P. Harsha
Publikováno v: Journal of Failure Analysis and Prevention. 21:2256-2277
In the present paper, the damage and life cycle of the last-stage blades (LSB) of a 250-MW low-pressure steam turbine are predicted under low-cycle fatigue conditions. A finite element-based analysis is carried out to compute fatigue life and damage

Vibration response analysis of sigmoidal functionally graded piezoelectric (FGP) porous plate under thermo-electric environment
Autor: S. P. Harsha, Pawan Kumar
Publikováno v: Mechanics Based Design of Structures and Machines. :1-31
In the present work, the vibration response of the porous functionally graded piezoelectric plates with electro-thermal loading using finite element formulations has been studied. A sigmoid law is ...
