Keywords : maximum deformation, maximum stress, and optimization Abstract :In every industry the source of power is supplied through mechanical, electrical or through fluid power. Compared to electrical power and mechanical power the fluid power is most suitable. Now a days in majority of the industries, the hydraulic power is used widely as the source of power. The hydraulic applications make way into, from basic agricultural field to advanced aerospace industries. Fluid power control is developed by increasing the parameters like mass, power, high speed and greater accuracy. In some applications like automatic fire control, machine tools, and flight control it is needed to achieve the faster control at high power levels, so this can be done by combination of hydraulic servo mechanics and electronic signal process. In electronic field it is easier to generate, transduce and process the signal than in the mechanical and fluid signals. The electro hydraulic servo mechanics provide more efficient, more reliable and faster devices. The electro hydraulic servo valve is the main component in this mechanism that accurately controls the flow of liquid in hydraulic system. The analysis and optimization of the valve has been done with the help of ANSYS software. Valve is designed and checked properly to achieve the requirements. Before optimization the mass of the valve was 141.81 gm and after optimization the mass of the valve is reduced to 72.77gm. Optimization is done by removing the excess material in the valve. After optimization we got maximum stress induced in the valve is 34.434 MPa which is less than the yield stress (310MPa) of the material. In addition decrease in size of valve leads to failure of the component, large deformations are induced. The total weight reduced is 69.04 gm. Hence the cost is saved by Rs 310680 per year.
