Optimizing for Robust Design #4

It’s time for another workout, so we let loose our optimizer on the tracks running one more extremely short turnaround to get the ECU (‘Electric Control Unit’) into better shape.
We unleashed the algorithm’s potential to leverage the design space by dropping the various manufacturing constraints. But we were adamant that we expected unmatched performance of the design as to stiffness, compliance and modals.
The animation below compares designs from the previous rounds #1 through #3 with deformations and von Mises stress levels during a transient forced response analysis. This load case corresponds to a vertical (Z) shock wave event 4G acceleration and an 11ms half-sine wave input excitation.
Unfasten the leash and get into an optimised shape better!
