Visualization of Strain influence on cutting edge of different Austempered Ductile Iron (ADI) products: FEA in Dozer Blade with ANSYS R 15.0

摘要

This paper presents the calculation of strain developed in the dozer blade cutting edge. The experimentation was done to determine the level of strain on different grades of ADI. The Finite Element Analysis (FEA) approach was used to determine the strain. The methodology was that a 3D model of dozer blade cutting edge is prepared in CATIA V5 with standard dimensions and then it is imported in ANSYS 15.0. The eight-node three-dimensional brick type elements are used during analysis. The properties of different grades of ADI are as per American Society of Testing and Materials ASTM A897M-90 standards. The meshing of dozer blade cutting edge model is done and for the strain the digging forces being applied at the tip of the cutting edge. The calculations of the strain on different grades of ADI are based on the maximum distortion energy theory (MDET). Subsequent to findings of the strain for the different ADI grades a best suitable grade is recommended for this particular application.
