Design optimization of CAD model

Abstract

This paper demonstrates the optimization process of a CAD model using the results of CAE Simulation result and computation in MathCad as an integrated approach. MathCad is generally used for calculations that take input from either dimensions of the CAD model or user defined parameters in CAD environment of Creo. The technique described here links the Creo Simulation result as the input in the PTC MathCad, while the output of this program is again directed to Creo Parametric and using this output result the CAD model is optimized. This process is a seamless integration of CAD model, CAE result and a MathCad computation using CAE results. To demonstrate this technique a mirror (used in space telescope) is selected and the aim is to find out the optimum location of mounting points that give minimum surface figure distortion under gravity loading. To check the trueness of this result, it was reviewed against the theoretically calculated values and it was observed that the optimized result was similar to the theoretical one.
