Aerodynamic characteristics on a full-scale high-speed train bogie with rotating wheelsets

Key Points

• Aerodynamics in a high-speed train bogie affects overall performance, particularly with rotating wheelsets.
• The analysis demonstrated that rotating wheelsets can reduce aerodynamic drag by significant percentages.
• Assessment includes flow visualization techniques to evaluate drag and lift forces in real-world conditions.
• Findings support improvements in design and efficiency for high-speed rail systems, emphasizing the importance of aerodynamics.
