    Abstract

    In this paper optimization process was performed to have light component. Shape optimization was applied to front rear spindle in order to reduce its mass. Finite Element software, Hypermesh was used for preprocessing procedure and Hypermorph used to define the shape variables to have the optimum results for the front rear spindle. The optimization solver Optistruct used to solve the problem with maximum stress equal to yield stress as a design constraint to make sure the redesigned shape’s stresses will not exceed the yield point. The results of the optimization process showed that the mass reduction using Optistruct was 8.37% of the original mass because of the limited changes due to the design space constraint. Mass reduction depends on the design space while the stress can be used as a controlling constraint to the optimization process. Reduction in weight for automotive industry will have good impact by saving more material, reduce cost and produce efficient cars.
