Designing and Groove Shaft Analysis under Different Loading Condition
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2017, Vol 5, Issue 5
Abstract
shaft is a critical and standard component which is used normally in all kind of industries for power/motion transmission. The discontinuity present in shaft is prime cause for failure of shaft. Discontinuity results in reduction in strength of shaft. Discontinuities are stress raisers which are responsible for the cause of fracture. The objective of this study is to design the solid shaft with single discontinuity present in shaft under different loading conditions. Based on the equations of stress concentration factor and conventional peterson’s curves and roark’s curves the design of shaft at critical locations is done in this study. The equations of stress concentration factors for groove are presented and used for the stress calculation purpose. The programs for every loading conditions are generated using matlab and variation of groove radius is plotted which is useful to obtain stress concentration factor for any step ratio. The final plots for step ratio and stress concentration factor at limiting condition are plotted which are quite useful to obtain minimum stress concentration factors for any d/d ratio at h = r condition and finite element analysis (fea) is performed to obtain the variation of stress magnitude at critical locations of shaft. The load is applied to the fe model in ansys, and boundary conditions are applied according to the shaft mounting conditions. The analysis is done for finding critical location in shaft. Fea carried out to find maximum stress at the critical location of shaft.
