Abstract

The paper describes Mixed-Integer Nonlinear Programming approach (MINLP) to the synthesis of large scale mechanical structures. The MINLP optimization approach is performed through three steps. The first one is a generation of a mechanical superstructure of different topology and standard dimension alternatives, the second one is a development of an MINLP model formulation and the last one is a solution of the formulated MINLP problem. The Modified Outer-Approximation/Equality-Relaxation algorithm and a Linked Two Phased MINLP Strategy have been proposed to solve large scale mechanical problems. A practical example of the MINLP synthesis of the three-element hydraulic steel gate structure Intake Gate in Aswan indicates that significant savings can be
