Surrogate-based multi-objective nose shape optimization for 400 km/h-class high-speed trains under open-air, crosswind, and tunnel operations

Abstract This study presents a surrogate-based multi-objective nose shape optimization for a 400 km/h-class high-speed train, considering normal open-air, crosswind open-air, and tunnel-related scenarios. The KTX-Cheongryong nose shape is parameterized using Bézier curves and a s...
