Influence of Secondary suspension, Bending stiffness, and Suspended under-chassis Equipment on First Bending Vibration of a Scaled Railway Carbody Model

Key Points

• First bending vibration increases with variations in bending stiffness, highlighting structural considerations.
• Key metrics indicate a significant correlation between secondary suspension design and vibration levels, impacting stability.
• Observational analysis of a scaled railway carbody model assessed the influence of under-chassis equipment on vibration patterns.
• Findings suggest potential design modifications to enhance railway carbody performance and reduce vibration issues.
