Abstract

Optimization problems are frequently not straightforward. This is due, among other reasons, to the predefined design constraints and simultaneous target goals that have to be satisfied. In addition, uncontrollable variations can influence the robustness and stability of the design. Moreover, engineers often have to optimize mechanical components that are part of complex assemblies, in which it is difficult to extrapolate and define the boundary conditions to be applied for component optimization. Aim of this work is to present a step-procedure for multi-goal optimization of components that are integrated in multipart engineering systems. In order to illustrate the method, optimization of a carry-mould, part of a blowing machinery composed by several components, was used as test case. Minimization of the carry mould moment of inertia and global mass were imposed as the target goals of the optimization process, while the maximum allowable displacement was set for a number of control points. The proposed procedure was able of a time efficient and cost saving extensive investigation of optimization design space.
