Adaptive Ensemble Surrogate Models for Mechanical Engineering Applications
Researchers at Zhejiang Science Technical University in Hangzhou, China, have developed a novel approach to enhance the accuracy and efficiency of adaptive ensemble surrogate models (AESMs). The study proposes an adaptive ensemble surrogate model based on fuzzy C-means (FCM-AESM) and a parallel adaptive infilling (PAI) strategy to optimize new samplings and eliminate points in close proximity. The FCM-AESM demonstrates superior model prediction performance, and the ES-PAI strategy exhibits greater robustness and outperforms individual adaptive infilling (IAI) strategies.
Key Takeaways:
- The FCM-AESM is initially proposed to enhance the accuracy of AESMs in practical engineering applications.
- The FCM-AESM improves the modeling method for AESMs and its IAI strategy by applying FCM analysis to the initial training set.
- The ES-PAI strategy optimizes new samplings and eliminates points in close proximity based on the Euclidean distance criterion.
- The ES-PAI strategy consistently surpasses IAI strategies in both global and local performance and exhibits greater robustness.
- The FCM-AESM method assisted by ES-PAI reduced the weight of a forklift gantry by approximately 22.18% while satisfying stress and deformation constraints.
- The research has been peer-reviewed and implemented in the multiobjective optimization (MOOP) of a forklift gantry.
- Authors of the research include Liye Lv, Tingxuan Yang, Yujun Lu, Wei Zhang, and Zhiwei Xiong.
