• Structural Topology Optimization Using Discete Structural Elements (In the Case of Beam Elements with Ellipsoidal Cross-Section)

抄録

This paper presents the outcome of research concerning the development of a structural topology optimization methodology which can be used at the conceptual design phase of mechanical products. This optimization method is constructed based on beam elements with ellipsoidal cross-section. First, the optimization problem is formulated for the stiffness maximization problem, and its algorithm is constructed based on the ground structure approach and the convex approximation method. The update procedure of the rotational angle regarding the principal direction of second moment of inertia in ellipsoidal cross-section is derived form KKT-conditions. In addition, several examples are provided to show the utility of the methodology presented here.
