Multi-Objective Design Optimization of Non-Pneumatic Passenger Car Tires Using Finite Element Modeling, Machine Learning, and PSO/Bayesian Optimization Algorithms
This study introduces an integrated generative-design and machine-learning-driven framework to optimize UPTIS-type spoke geometries for passenger vehicles. By combining FEM, ML models (KRR for stiffness, XGBoost for durability and vibration), and optimization algorithms (PSO, Bayesian Optimization), the framework significantly enhances tire performance with improved stiffness tunability, durability, and reduced vibration.

PSO vs. BO in Multi-Objective Optimization
This study compared Particle Swarm Optimization (PSO) and Bayesian Optimization (BO) for multi-objective optimization of NPT spokes. While BO excelled in global exploration, mapping diverse design configurations, PSO demonstrated superior local exploitation, leading to sharper convergence and higher-quality Pareto fronts with optimized stiffness, durability, and vibration characteristics.
Impact: PSO consistently achieved higher gains across stiffness tuning, durability enhancement, and vibration minimization compared to BO. This highlights PSO's efficiency in converging to optimal solutions, especially when precise performance goals are critical.
