A new mathematical model is put forward numerically to simulate the wheel ovalization.. In the numerical simulation, the dynamic model of a half railway vehicle coupled with a tangent track is employed. Using the new numerical method investigates vehicle-track coupling system dynamic responses including lateral and vertical displacement of wheelsets and the vehicle, lateral and vertical vibration acceleration of the track at different phase angle of the two side wheels of the same wheelset, which are compared with that of the traditional model. The numerical results show that the discipline and frequency of dynamic responses are accordant, amplitude and phase of lateral dynamic responses are different. It is concluded the traditional track geometric irregularity excitation model does not simulate the effect of periodic wheels ovalization on vehicle-track coupling system dynamic behavior truly, the new model is more accurate and reasonable.
本文研究了车轮二阶周期性非圆化—椭圆化,建立了一个新的模拟车轮椭圆化的数学模型,结合车辆-轨道空间耦合动力学模型,计算了同一轮对左右车轮不同相位和车轮椭圆度下轮对和车体的横、垂向位移,钢轨横、垂向振动加速度,并与传统模型计算结果作了对比,分析表明两种模型的动力响应变化规律和频率一致,但横向动力响应幅值和相位均存在不同程度不可忽略的差异,因此传统的轨道几何不平顺激励模型不能真实模拟车轮的周期性椭圆化对车辆-轨道耦合动态行为的影响,而本文模型更能反映实际椭圆车轮与钢轨接触情形,计算方法准确而合理。
