摘　　要：利用MATLAB中频域内虚拟激励的分析方法,得到在不同车速及抗蛇行减振器节点刚度下前、后转向架主要横向振动部分的位移和加速度响应的功率谱密度值。经研究发现,车速是影响前、后转向架位移和加速度功率谱密度值的主要因素。在不同频率范围内,不同节点刚度值对功率谱密度值的影响各有差异,其节点刚度参数对功率谱密度值的影响主要表现在低频范围。转向架横移、侧滚加速度功率谱密度变化相对于抗蛇行减振器节点刚度的取值非常敏感,而合理地降低抗蛇行减振器橡胶节点刚度有利于提高转向架的横向运动平稳性。In this paper,through the MATLAB program,the virtual excitation analysis method in the frequency domain is used to obtain the power spectral density values of the displacement and acceleration responses of the main lateral vibration parts of the front and rear bogies under the different vehicle speeds and anti-yaw damper joint stiffness.The study found that the vehicle speed is the main factor affecting the front and rear bogie displacement and acceleration power spectral density values.In the different frequency ranges,the influence of different joint stiffness on the power spectral density values is different,the influence of the joint stiffness parameters on the power spectral density value mainly appears in the low frequency range.The variation of the power spectral density of the bogie lateral displacement and roll acceleration is very sensitive to the value of the stiffness of the anti-yaw damper joint,and reasonable reduction of the rubber joint stiffness of the anti-yaw damper is beneficial to improve the lateral stability of the bogie.
