Abstract: The paper deals with the design optimization of a bracket with Finite Element Analysis using ANSYS software. A procedure has been developed for the optimum design of a bracket in ANSYS software. The function design emphasize that structure will not fail, but some aspects like dimensions of structure can also be improved. In the paper, the volume of a bracket is optimized. A mathematical model is developed for the bracket based on its volume. It consists of objective function, design variable and state variable. ANSYS software is used to find the result in which the safe designing will be done by the help of the optimization algorithm. A series of the analysis were carried out searching for the minimum volume by changing the dimensions each time. A best design set is obtained from many feasible design sets. The best design set gives the best dimensions of the chosen parameter resulting in the optimized volume at the same strength. The optimized volume resulting the saving in structural weight
