A crane pedestal and its reinforcement structure are analyzed using finite element software as to predict and improve its structural behavior before a prototype is built. This application note shows how Optimus is used with MSC Patran, MSC Nastran and an in-house software to identify the sensitivity of the static characteristic to the geometry and topology variation of the structure, and to reduce maximum stresses.

The problem

Finite element software is used to simulate structural behavior based on input data provided by engineers. Unfortunately, this approach can only be used to validate designs. If the objective is to optimize structural behavior and to minimize stress peaks, Optimus is needed to explore the entire design space, to provide deeper engineering insights and to identify designs that meet or even exceed design specifications. As a first step Optimus is used to capture the engineering workflow, including all software codes as well as the related input and output files.

Solution approach

By capturing and automating the engineering process involving MSC Patran, MSC Nastran and an in-house developed code, Optimus deliversg a repeatable simulation process - freeing the engineer from repetitive administration tasks and delivering the information that is needed to gain deeper engineering insights. Optimus can then quickly identify the sensitivity of structural properties related to a variation of the design parameters, at a limited computational effort. And finally, using a selection of Design of Experiments and Numerical Optimization techniques, Optimus is able to identify design parameter values that reduce maximum stress by 12.7% - all of this in a fraction of the time required with conventional solution approaches.
