Tools of Computer Aided Engineering (CAE) are widely employed in many mechanical industries such as automotive industries. However, most mechanical design engineers, in fact, do not utilize CAE applications by themselves in the design phase because of the sophisticated operations and a huge amount of time for the analysis. Recently, the concept of a new CAE, First Order Analysis (FOA), has been proposed in order to overcome these problems. In this paper, we present a structural topology optimization method based on this concept. First, a multi-objective optimization problem to deal with the multiple loading problem is formulated. Next, the optimization procedure is developed based on the ground structure approach. Finally, some examples are provided to confirm the optimization method proposed here.
