高速车辆拖动式独立车轮轮对的研究(待续)

Research on Independent Wheelsets of Trailing Mode for High Speed Cars

独立车轮转向架在高速车辆中有良好的发展前景 ,但由于缺乏直线复位和曲线转向能力 ,长期没有得到普及和推广。本文通过理论分析和动力学计算表明 ,采取适当措施使独立车轮轮对以拖动的形式前进 ,可以有效解决独立车轮的导向问题。拖动式独立车轮轮对在直线上复位可靠 ,在曲线上借助径向调节装置能够近似地处于轨道的径向位置 ,与传统轮对比较 。

The bogies with independent wheels have a bright development prospect in high speed cars.But since their repositioning on tangent track and steering on curve line are not reliable enough,they have not been applied and developed on a large scale for a long time.Theoretical analysis and dynamic calculation in this paper show that application of proper measures to make the independent wheels move in the trailing way can solve the problem of guiding for the independent wheels effectively.The trailing mode wheelsets with independent wheels can reposition reliably on tangent track,and be in the radial position on the curve track with the help of the radial adjusting device.The lateral dynamic performance has been improved greatly in comparison with traditional wheelsets.
