Dynamic Analysis of Hydraulic Cylinder of JCB JS

Abstract- Many machines and machine mechanisms run under dynamic working conditions. The vibrations produced under dynamic conditions affect many important design parameters such as strength, production costs, productivity. In this dissertation work, the vibration analysis of a hydraulic cylinder subjected to dynamic loads is studied. Computer aided engineering (CAE) procedures are used to analyze the dynamic response of the cylinder walls. The finite element methods used in the analysis are applied by a computer aided design and analysis software ANSYS. First of all, the vibration under the moving load problem is studied. The vibration of simply supported beam under a moving point load is analyzed by using ANSYS. In addition to studies in the literature, it is considered that the static and dynamic analysis of the hydraulic cylinder by applying of operating pressure and hydrostatic pressure respectively justifying behavior of both pressure in cylinder. Also identifying which boundary condition will suitable for sustaining and minimum failure occur by evaluate simulation result of ANSYS such like total deformation, deformation in X-direction, Y-direction and Z-direction. Also identifying modal analysis of hydraulic cylinder in both conditions.
