[Example] Shape optimization to match the natural frequency with experimental measurement results.

Efficiently considering multiple constraints, control the eigenvalues of automotive brake components!

We present an analysis example applying the non-parametric shape optimization function of "OPTISHAPE-TS," which employs an algorithm based on the smoothing gradient method (force method) to match multiple natural frequencies in automotive brake components. The optimization conditions were set to target the natural vibration modes from the 7th to the 21st, aiming to match their natural frequencies to the target values (considering MAC values) while keeping the volume unchanged. As a result, a final shape was obtained where each eigenvalue and volume matched their respective constraint values with an accuracy within 0.01%. In this case, the control of eigenvalues was performed using specified initial shape ratios, but analyses can also be conducted using absolute values or combinations of other controls such as nodal positions of natural vibration modes and frequency responses. This can be utilized for controlling eigenvalues and avoiding resonance. For more details, please refer to the PDF materials or feel free to contact us.
