介绍径向转向架在城市轨道交通中的发展，阐述了不同转向架通过小半径曲线的导向机理。重点介绍了日本东京地铁最新研制、采用的半迫导型径向转向架及其模拟试验、现车对比试验、噪声监测试验与评估。其新型转向架在降低轮轨磨耗量、降低车内噪声等方面效果明显。%The development of radial bogie in urban transit is introduced. The steering mechanism of different bogies negotiating a sharp radius curve is stated. Focuses are on the latest development of the Tokyo metro in Japan, the forced radial bogie and its simulation test, prototype comparison test, test and evaluation of noise monitoring. The new bogies reduce wheel rail wear and interior noise effectively.
