Optimal reliable design of brake disk using a Kriging surrogate model

In this article, structural analysis is performed on the disk due to the brake pad actuating load. Thermal analysis is addressed on the disk to observe the maximum temperature rise after the braking operation. A reliability-based design optimization using Kriging meta-model is performed to determine the optimal reliable design. Kriging meta-model provides a more accurate approximation of the original model with 50 LHS points. The objective is to minimize the brake disk volume, whereas the constraints are to minimize its stress and temperature. The optimal design gives a minimum volume with a weight reduction of 32.67% compared to the initial model.
