Optimal Vibration-Absorber Design: A Case Study on Railway Trailing Arm Bush

The wheel-rail surface damage in curves can be significantly reduced by lowering the Primary Yaw Stiffness (PYS), though a reduced PYS may impact passenger comfort when using conventional trailing arm bushes—a primary suspension component in railway vehicles. Prior research indicated that a hydraulic-damping-integrated trailing arm bush could mitigate the compromise...
