摘要

This paper utilizes the ANSYS Workbench platform to establish a shaft disc brake finite element model, aiming to analyze braking noise. By thoroughly examining the impact of the shape and arrangement of brake friction blocks, extensive simulations reveal significant variations in noise levels among different configurations. These findings offer valuable insights for the design of CR450 EMUs brake pads.
