Optimising for Robust Design #4

04 June 2021

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