介绍了用传递矩阵法（TransferMatrixMethod）求取考虑了转向架构架弯曲刚性的转向架、车体的振动响应解析方法，并以日本新干线动车为例，计算了与轨道垂直变形相对应的车体振动响应。在此基础上，研究了转向架构架弯曲刚性等转向架参数对车体弯曲振动及垂向系统乘坐舒适性的影响。研究结果表明，转向架构架的弯曲刚性对车体的一次弯曲振动影响不大，但转向架构架刚性降低会导致10Hz以上高频区二次以上的车体弯曲振动加大，使乘坐舒适性恶化。文中还阐明了转向架轴距、轴弹簧等参数对乘坐舒适性的影响。
The transfer matrix method (TransferMatrixMethod) is introduced to analyze the vibration response of the bogie and vehicle body considering the bending rigidity of the bogie frame. Taking the Japanese Shinkansen as an example, the calculation of the bodywork corresponding to the vertical deformation of the track Vibration response. Based on this, the influence of the bogie stiffness such as bogie frame on the bending vibration of the car body and the ride comfort of the vertical system is studied. The results show that the flexural rigidity of the bogie frame has little effect on the flexural vibration of the vehicle body. However, the decrease of the rigidity of the bogie frame will lead to the increase of the bending vibration of the vehicle body more than 10Hz in the high frequency region, which will deteriorate the riding comfort . The article also clarifies the bogie wheelbase, shaft spring and other parameters on the ride comfort.
