Abstract ∵ The bogie frame is an important part of the process of transferringwheel-rail excitation energy to the vehicle body. Itis crucial to implement appropriate damping measures for suppressing high-frequency vibrations in the bogie frame.This study investigates the vibrationsuppression effectiveness of a high-speed train bogie frame based on particle damping.The frequency range and optimal installation position of the particle damping structure is determined by combining line test data with finite element analysis.A discrete element model isestablished to evaluate energy dissipation under diffrent design schemes，analyze the underlying mechanism，and obtain optimal parameters for particle damping based on comparative energy dissipation analysis. The steady state energy flow method is employed to calculate the equivalent damping coefficient ofparticle damping using information on energy disspation，velocity，and mass.This effect is further validated through finite element modeling ofthe frame.Finite element analysis resultsdemonstrate a significant reduction in acceleration response at axle box seat of the rotor upon addition ofa particle damping structure. Key words ∵ bogie frame ;particle damping; discrete element; ; steady state energy flow method

在列车高速运行过程中，轮轨激励能量大，频带宽，激励频率高，由于轨道的吸能性较差，能量很容易传递至转向架区域以及车体内部，从而引发车辆关键零部件疲劳开裂、转向架构架疲劳损伤、车内噪声超标等问题，从而显著影响高速车辆的动力学性能、疲劳寿命以及乘客舒适性[1-6]

通过对传递路径分析，轮轨激励能量首先传递至转臂轴箱上，经由一系悬挂元件传递至构架，构架再通过二系悬挂以及牵引拉杆传递至车体地板。（剩余6485字）
