The mounting bracket is one of the most important connecting components in commercial vehicle cab. The FEM provides guidance for maximizing the effectiveness of weight reduction efforts on condition that the structure meets the requirements for strength, stiffness and vibration performance. The work presents two kinds of structural optimization methods, which are topology optimization and size optimization respectively, and introduces how to perform a sensitivity analysis before a size optimization. The two optimization methods are realized by using Altair's OptiStruct. The results show that it is a more efficient way to reduce the weight of the bracket by using topology optimization, and the size optimization produces a shorter solving time than topology optimization.
