摘要

轮轨噪声随着列车运营速度的提高而显著增大,综合应用车辆-轨道耦合动力学、随机振动理论和声辐射理论,预测由轮轨表面粗糙度、接触不连续几何缺陷等激起的高速列车轮轨噪声,建立轮轨噪声预测模型,并开发相应软件WRNOISE(Wheel/rail Noise)。与已有的轮轨噪声预测模型TWINS(Track-Wheel Interaction Noise Software)比较,预测的噪声主频和变化趋势与TWINS的预测结果一致;与STTIN(Simulation of Train-Track Interaction Noise)模型相比,预测模型考虑车轮辐板和钢轨轨腰横向振动噪声的贡献;与有砟和无砟轨道路基区段噪声实测结果的对比表明,WRNOISE模型计算结果与实测结果仍存在一定差异,但从轮轨噪声辐射主导频率看,变化趋势基本一致。
With the rising of train operation speed,wheel/rail noises are significantly increased.Based on vehicle-track coupled dynamics,random vibration theory and acoustics theory,a model is produced to predict wheel/rail noises by high speed train operating due to wheel and rail surface roughness,geometric discontinuity in contact,and so on.And the corresponding software WRNOISE(Wheel/Rail Noise)is developed.Compared with existing prediction model TWINS(Track-Wheel Interaction Noise Software),the result shows that the main frequency ranges and trends of the noise of TWINS software simulation values and the present model computation values are consistent.Compared with the model STTIN(Simulation of Train-Track Interaction Noise),the present prediction model can be more fully taken into account the vibration and noise contribution in the axial direction of wheels and the lateral direction of rails.Compared with the noise test values of the high-speed train running on ballasted track and slab track,there are some differences between prediction values of the present model WRNOISE and noise test values,but both trends are in agreement mutually from the viewpoint of wheel-rail noise radiation dominant frequencies.
