Abstract: The economic practice of rapid rails was to settle the self-stability problem of wheelsets more economically,but its limited velocity was difficult to be broken through.For the stability and safety practice of high-speed rails,the instability hunting oscillation phenomena of whole high-speed bogie should be solved with lead-lag correction,and the nominal equivalent conicity was therefore decreased to 0.10 and the long routing crossover lines could be performed more efficiently.To overcome the design defaults of ICE3 bogie prototype,the solution was presented based on serial combination of anti-yaw dampers for eliminating the following negative effects,i.e.the conditionality to wheel-rail matching,the sensitivity to rail wear and the lateral vibration coupling mechanism.The serial combination applications of T60 and T70 could be implemented by applying with the redundancy design of anti-yaw dampers.Through the optimal configuration of anti-hunting parameters,the complementarity of low-frequency structural damping and high-frequency impedance interaction could be formed which had the similarity of lead-lag correction.By applying this similarity,the optimal configuration of long train bogies could be formulated,which could improve and enhance the adaptability,friendliness and stability robustness to railway lines and technical service conditions.

Key words: ICE3 serial bogies, instability hunting oscillation of whole bogies, lead-lag correction, long routing crossover lines, optimal configuration of long-train bogie

摘要： 快铁经济运用要更加经济地解决轮对自稳定问题,其极限速度难以突破。高铁稳定安全则要对高速转向架不稳定蛇行振荡现象进行超前滞后校正,名义等效锥度降低至0.10,更好地实现长交路跨线运营。为了克服ICE3转向架原型设计缺陷,尽量消除其对轮配条件制约性、钢轨磨耗敏感性和横向振动耦合机制的负面影响,提出了基于抗蛇行并联组合应用的解决方案。借用抗蛇行冗余设计形式实现T60与T70并联组合应用;通过抗蛇行参数优配形成低频结构阻尼与高频阻抗作用的互补性,使其具有超前滞后校正的相似性。利用这一相似性制订长编转向架优配方案,改善并增强对轨道线路及其服役技术条件的适应性、友好性和稳定鲁棒性。
