项目摘要

This study aims to analyze fundamental dynamical characteristics of a tilting railway vehicle using variable link mechanism for compensating both lateral acceleration that passengers feel and wheel load unbalance between inner and outer rails.In the first part, geometric relations between the center of rotation and the center of gravity and positions of four-links were analyzed. Then equation of the pendulum motion of railway vehicle body with four-link mechanism was derived for analyzing dynamic stability and natural frequency of the pendulum motion that depends on the link parameters as well as vehicle body parameters. Using these equations, lateral acceleration acting on the vehicle floor and unbalanced wheel load between inner and outer rails were theoretically studied and the natural frequency of the pendulum motion was theoretically obtained. These geometric and dynamic models of the tilting railway vehicle using link mechanism were verified by experiment results.In the second part, theoretical analysis is conducted to find "perfect tilting condition", that is, a geometric parameter set of link mechanism that can provide both zero lateral acceleration and zero wheel load unbalance simultaneously. This perfect tilting condition can be obtaine by changing the variable length of linl mechanism.Finally, to realize the perfect tilting condition on curved section, feed-forward and feedback compensations for the variable link mechanism are applied to this tilting vehicle body system. The experimental set-up that is excited by hydraulic actuators is used to simulate the dynamic characteristics of the tilting vehicle body on the curved track. Computer simulation is carried out to verify the effectiveness of this system by comparing with the experimental results.

本文针对采用可变连杆机构的摆式列车，分析了其基本动力学特性，并对车体的转动中心、重心和四连杆位置之间的几何关系进行了分析。在此基础上，推导了四连杆机构铁道车辆车体的摆运动方程，分析了摆运动的动态稳定性和固有频率与连杆参数和车体参数的关系。利用这些方程，对作用在车辆地板上的横向加速度和内外轨间的不平衡轮载进行了理论研究，并从理论上得到了摆运动的固有频率。第二部分通过理论分析，寻找“理想倾摆条件”，即能够同时实现零横向加速度和零轮重不平衡的连杆机构几何参数集。最后，为了实现曲线段的最佳倾摆条件，将变杆机构的前馈和反馈补偿应用于该倾摆车体系统。采用液压作动器激振的实验装置，模拟了倾斜车体在曲线轨道上的动力学特性。通过与实验结果的比较，验证了该系统的有效性。
