A Stress Analysis on Railway Axle With Fatigue Crack Growth.

This paper present the analytical method of a railway axle using three different load at a constant speed. Very rare case is may be possible, Train is running condition then suddenly apply the break and one wheel is stationary condition and second wheel is rotating in some angle (angle of twist). To estimate maximum shear stresses, 3D models are generated by modeling software CATIA V5 and simulation is done by finite element software package ANSYS 14.0.What the effects on axle in ANSYS and find out the maximum shear stress. Material used for Axle is high carbon steel..Analytical method of calculating maximum shear stress uses general theory in shear stress in shaft. NOMENCLATURE: z : Torsional Shear Stress θ : Angle Of Twist R : Radius Of The Shaft T : Twisting Moment J : Polar Moment Of Inertia C : Modulus Of Rigidity L : Length Of The Axle P : Force N : No of Speed T : Torque d : Diameter Of The Shaft
