文章统计分析了国内主型客车转向架的历次动力学试验数据,并指出各型转向架具有不同的振动特性。为满足较高运行速度下的性能要求,对206型转向架可侧重研究提高横向振动性能,对209型转向架可侧重研究提高垂直振动性能。对于空气弹簧转向架,则必须研究具有小横向刚度的悬挂结构。
The paper statistically analyzed the previous dynamic test data of domestic main bus bogies and pointed out that each type of bogie has different vibration characteristics. To meet the performance requirements at higher operating speeds, the 206 bogie may focus on research to improve lateral vibration performance, and the 209 bogie may focus on research to improve vertical vibration performance. For air spring bogies, it is necessary to study suspension structures with small lateral stiffness.
