TKZ9 型客车转向架中央悬挂装置的结构设计与参数选择

Structural Design and Parameter Selection for Central Suspension on Passenger Car Bogie TKZ9

中央悬挂装置采用外侧悬挂弹性长吊杆、横向油压减振器、自由膜式空气弹簧、抗侧滚扭杆装置、全旁承支重结构及弹性中心销牵引装置等新技术。同时，对弹簧刚度、减振器阻尼等各项主要动力学性能参数进行了优化选择。整车动力学试验结果表明，达到了预期的效果。

New techniques are applied on the central suspension device,such as the outside suspended elastic long hanger rod,cross oil damper,free film type air spring,rolling resistant torsional bar,fully side bearing loaded structure and elastic center pin traction device.In the mean time,the main dynamic performance parameters,such as the spring rigidity,oil damper damping,are optimized and selected.The dynamic test for integral cars shows that the expected results has been obtained.
