CRANKSHAFT ANALYSIS AND MODELING USING ANSYS SOFTWARE

Abstract

The reliability of any system, during which the linear displacement of a piston is regenerate into the rotation of a power transmission shaft, strongly depends on the reliability of the crankshaft. The crankshaft is that the vital element and any damage occurring to the crankshaft might put the system out of order. Crankshaft is massive volume production component with a complex geometry within the ICE. This converts the reciprocating displacement of the piston into a rotation of the crank. The crank shaft takes the power from piston that is generated because of combustion method within the combustion chamber of the cylinder. Throughout the power transmission method the load acts at a specific crank angle to the max and thus the connecting rod is analyzed for the stress developed, due to load conditions and the changes mentioned. The existing works design first the 3D model of the engine parts are built in the software ‘CATIA V5’ and are then transferred to ‘ANSYS’. The analysis of crank throw distortion and stress provides a conceptual support to enhance the design by weigh reduction. The proposed research works the 3D model of crankshaft system, obtained from CATIA V5 software is analyzed in ANSYS to assess the motion and loads acting on the crankshaft. Topology optimization is help to optimize the performance of any machine. The present model is test in three different loading conditions 22624N, 32624N and 42624N load is applied in crank shaft. After analysis ad comparison of all present models it is seen that the lowest stress, deformation and weight are found in model 3 in all loading condition. The topology optimization process is help to reduce the material of workpiece without affecting the performance.
