Multi-Objective Topology Optimization Design of a Large Marine Gearbox
Multi-objective topology optimization was studied for layout and structural optimization of a large marine gear-box to minimize its weight, while guaranteeing its strength and rigidity. After determining design domain and multiple load cases, static structure stiffness and the first order natural frequency was defined as optimization objectives. Based on SIMP(solid isotropic material with penalization) method, the topology optimization model of the box structure was set up. Furthermore, by taking into account of manufacturability, the optimal structure was obtained. Comparing to the original design, the optimized box has 7.8% weight reduction, while its structure is more reasonable, indicating the method has certain theoretical and engineering values.
