TAILIEUCHUNG - Fatigue analysis of out-put shaft subjected to pure torsion

In present study the failure of the shaft in the yaw gear box is analyzed .As we the shaft is rotating part of the engine it transmit the power from the one part of the engine to another part. | Fatigue analysis of out-put shaft subjected to pure torsion International Journal of Mechanical Engineering and Technology IJMET Volume 10 Issue 04 April 2019 pp. 9-16 Article ID IJMET_10_04_002 Available online at http ijmet JType IJMET amp VType 10 amp IType 4 ISSN Print 0976-6340 and ISSN Online 0976-6359 IAEME Publication Scopus Indexed FATIGUE ANALYSIS OF OUT-PUT SHAFT SUBJECTED TO PURE TORSION Nagaraj S B M Tech Student Mechanical Engineering Dept Bengaluru India Chetan S Professor Department of mechanical Nitte Meenakshi Institute of Technology Bangalore India Shyamaprasad S Off-highway R amp D AVTEC Ltd Hosur Tamilnadu India Venugopal Nair AGM Off-highway R amp D AVTEC Ltd Hosur Tamilnadu India ABSTRACT In material engineering it is important to determine the cause of the failure amp prevention of the failure .In present day the failure of the machine component is about 90 of the failure is because of the fatigue. In present study the failure of the shaft in the yaw gear box is analyzed .As we the shaft is rotating part of the engine it transmit the power from the one part of the engine to another part. It holds the maximum stress. In this case shaft of heat treated component with ultimate tensile strength Su 2100Mpa is analysis done with ANSYS FEA software amp compared with the theoretical calculation. There are different methods which are used to predict fatigue life include stress life S-N strain Life E-N and Linear Elastic Fracture Mechanics LEFM . In this project study S-N approach is used to predict fatigue life for out-put shaft. Key words Shaft FEA-ANSYS SN-curve Fatigue life Fatigue factor of safety Fatigue damage Cite this Article Nagaraj S B Chetan S Shyamaprasad S Venugopal Nair Fatigue Analysis of Out-Put Shaft Subjected to Pure Torsion International Journal of Mechanical Engineering and Technology 10 4 2019 pp. 9-16. http IJMET JType IJMET amp VType 10 amp IType 4 1. .
