The development of optimum products in the automotive industry has a significant impact on the process product cost. For this reason, in the product design process, optimum design must be achieved. The method to choose during optimization studies is one of the most important elements in achieving optimum design. In this context, it is very important to choose the methods that are optimum to the point and converge correctly. In this study, the swing arm used in the front suspension system of the automobiles was optimized by topology and shape optimization respectively. The newly introduced internal search algorithm for shape optimization has been used in the literature for the first time in the optimum product design process.
