Research on Vertical Vibration of Secondary Suspension with Air Spring of High-speed Train
建立空气弹簧系统垂向非线性动力学模型和某高速列车动力学模型,根据空簧垂向振动传递试验结果,验证空簧非线性动力学模型的准确性,采用数值仿真分析空簧的垂向动刚度特性和振动传递规律.研究二系抗侧滚扭杆刚度、空簧节流孔直径和二系垂向减振器阻尼对振动传递规律的影响,对比不同二系悬挂结构对车辆动力学指标的影响,发现节流孔直径对空簧动刚度和传递率影响很大,减小节流孔直径会增大空簧垂向动刚度;采用节流孔方式有利于改善高频减振效果,采用二系垂向减振器有利于低频减振…查看全部>>
