Finite Element Analysis of Two-Crack Shaft in a Rotor Disc-Bearing System

Authors(2) :-Avinash Bajpai, Pradyuman Vishwakarma

The current analysis has bestowed a study of natural frequency characteristics of a shaft of various profiles. Structural steel and alloy 6061 system were used for this model analysis. The impact of diameter with totally different or completely different profiles of the Shaft without crack and shaft with two cracks on the natural frequency and modes of various materials and critical speed effects were analyzed on different profile and materials of shaft and distribution on the shaft was studied. The cluster of nodes and parts is understood as meshing this method is finished to determine convergence of solution the development convergence of solution may be a relation between accuracy, degree of freedom and no. of nodes and parts as the amount of nodes and parts are enhanced at variable iteration a convergence of solution is obtained. Meshing are of various varieties i.e. Tetrahedral, Quadrahedral, Hexahedral, square mesh and triangular mesh, tetrahedral mesh offers higher convergence throughout finite element simulation a stiffness matrix, damping matrix, stress matrix is resolved on ANSYS at each and every node and element by iteration strategies like runge-kutta etc. to determine convergence of solution.
