During the initial design of military vehicles, one of the most fundamental tasks is to meet the durability requirements with the minimum weight. The prototype of a Korean light tactical vehicle is a new car with a bulletproof glass and body to secure survivability, but with a greater total weight due to these structures. Thus, multidirectional actions have been taken to reduce the weights of non-bulletproof structures and to satisfy the total weight constraint. This paper suggests a design optimization process for weight reduction of the trimmed body and suspension arms of the new tactical vehicle. Inertia relief analysis and normal mode analysis of each part are conducted to determine the allowable stress and the natural frequency. Using the optimization analysis method (SOL200) in the MSC/Nastran software, the optimum thicknesses of 32 design variables are computed to extract the minimum weight within the strength and vibration constraints. Finally, durability analysis of the optimum model of each component is performed to evaluate whether or not it satisfies the target life.
