Abstract

The polygon effect seriously affects the running stability and safety of the vehicle. In order to suppress the wheel polygon, a dynamic model is established that can calculate the force on the resilient wheel's rim and core. With straight lines, curves, and vertical curves as input excitation, combined with wheel–rail force and acceleration, the suppression effect of the resilient wheel on the polygon is analyzed from the perspective of the time domain, frequency domain, and polygon order. The results show that the resilient wheel can effectively reduce the vertical wheel–rail force and restrain the wheel polygon. After 30 Hz, with the increase in frequency, the suppression effect of the resilient wheel on the polygon becomes increasingly significant. The resilient wheel can sufficiently suppress the polygons generated by 50–150 Hz carriage vibration without affecting the dominant frequency of carriage vibration. This study can provide a new idea for the suppression of wheel polygon.

多工况下弹性车轮多边形抑制研究

多边形效应严重影响车辆的运行稳定性和安全性。为了抑制车轮多边形，建立了可计算弹性轮辋和轮芯受力的动力学模型。以直线、曲线和垂直曲线作为输入激励，结合轮轨力和加速度，从时域、频域和多边形阶数的角度分析弹性轮对多边形的抑制作用。结果表明，弹性轮能有效减小轮轨垂向力，抑制车轮多边形。在30 Hz之后，随着频率的增加，弹性轮对多边形的抑制作用越来越显著。弹性轮能在不影响车厢振动主频率的情况下，充分抑制车厢振动50 ~ 150hz产生的多边形。该研究为车轮多边形的抑制提供了新的思路。
