Hydraulic machines are commonly placed in the industry of now a day. Study of vibrations in hydraulic cylinder is very much important in container lifting devices, which cause seal failure, reduction of fatigue life of cylinder, reduction on control, energy loss, increase in oil temperature results in low viscosity. To study the effect of vibration, root cause for vibration and identifying the natural frequency of hydraulic cylinder and also dynamic behavior of loading condition are required. Vibrations in hydraulic cylinder are multi degree of freedom problem. So, analysis of mode shapes of vibration is required. In this paper, modal analysis of container lifting mechanism was carried out in ANSYS workbench. Maximum deformation due to vibration has been studied and effect of angular movement of arm on natural frequency of lifting container is obtained through finite element analysis. As angle of arm increase, the natural frequency of mechanism is slightly increased.
