中文摘要：

由于ICE3转向架原型存在对轮配技术条件制约性,因而必须依靠原创性技术创新来转变客运专线发展模式.以长编转向架优配作为技改范例,应用抗蛇行宽频带吸能机制,实现了对转向架不稳定蛇行振荡现象的超前滞后校正,部分恢复了转向架自导向能力,克服了对轮配技术条件制约性,即名义等效锥度降低至0.10.如何实现车体与走行部横向解耦应当作为快捷与高速货车转向架的主要创新要素之一.若无抗蛇行减振器,则必须保障旁承摩擦及其回转阻力矩的稳定性,以降低结构性技术服务成本.参照Y37转向架及其TGV客货混用成功经验,合理确定快捷与高速货运的轮配技术条件,进而实现客货混用的＂高速度低影响＂技术目标.

英文摘要：

Due to the wheel-rail matching conditionality of ICE3 bogie prototype,the practice mode of dedicated passenger lines must be changed urgently by applying the technical innovations. Taking long-train bogie as technical improvemrnt paradigm,the lead-lag correction to hunting ocillation instability of bogies is realized by applying the anti-hunting absorting wide-band mechanism,and the self-steering ability of bogie can be then recovered partally so as to overcome the wheel-rail matching conditionality,i. e. nominal equilalent conicity is decreased to 0. 10. Meanwhile how to decouple laterally between carbody and running gears is one of innovative factors in developing projects of high-speed / rapid freight bogies. If no anti-yaw damper is adopted,the stability of side bearing frictions and resistance moments should be guaranteed correctly. With reference to the Y37 freight bogie and the successful experiences of TGV passenger-freight mixed mode,the nominal equivalent conicity can be selected rationally for both rapid / high-speed freight rails. So the technical objective of highspeed and low-impact can be achieved therefore for the mixed practices of passenger and freight transportions.
