Analysis of camshaft for straight line six cylinder's IC engine
Abstract
The camshaft is generally used in IC engine driven by crankshaft via timing gear to operate poppet values to control the flow of air/fuel mixture for suction and exhaust strokes of cylinders. The camshaft rotates at very high speed, critical loads causes vibrations in system and it is subjected to varying fatigue loads due to the contact of the follower on the cam. These critical values are needed to determine to avoid failures in camshaft. In this paper, six cylinder camshaft is modeled and analyzed by varying loads and torque with respect to speed and time. The 3D model of camshaft is designed in CATIAV5R20 modeling software. In this present work, existing material malleable cast-iron are replaced with different selected materials are Ni Cr Mo alloy steel, SS316, EN24T and C55Mn15.The dynamic analysis, Fatigue analysis and Modal analysis is carried out using ANSYS2019R2 software. Dynamic analysis is done to find the deformations, stresses and strains. Modal analysis is done to determine natural frequencies at different mode shapes and Fatigue analysis is done to estimate the life of the component. The simulated results are compared with theoretically calculated value and it shown good agreement.
