摘要
为完善运营速度290和300 km/h的高速列车轨道(桥梁)时变系统横向激振源的基础资料,基于实测的高速列车构架蛇行波资料,运用工程概率数值分析方法,对高速列车构架蛇行波标准差σ进行了统计,并运用三角级数模型及Monte-Carlo法随机模拟出高速列车人工构架蛇行波.研究结果表明,随着速度由290 km/h上升到300 km/h,高速列车构架蛇行波标准差σ_p(p=99%)由0.238 3g上升到0.245 1g,且高速列车人工构架蛇行波峰值分别为0.843g,0.883g,与实测构架蛇行波峰值接近,初步验证了构架蛇行波标准差σ_p的合理性,从而为高速列车轨道(桥梁)系统横向振动分析提供了良好的激振源.
To perfectng the fundamental data of the lateral exciting source of the high-speed train and track（ bridge） time-variant system at the speeds of 290 and 300 km / h,the standard deviation σ of the bogie frame hunting wave was studied based on the actual measured bogie frame hunting wave of high-speed train by the method of engineering probability numerical analysis. Meanwhile,the artificial hunting wave of the bogie frame for high-speed train was randomly simulated by the trigonometric series model and the Monte-Carlo method. The results showthat,when the speed increases from290 km / h to 300 km / h,the standard deviation σp（ p = 99%） of the bogie frame hunting wave is increased from 0. 238 3g to 0. 245 1g. The maximum values of the artificial hunting wave of the bogie frame for high-speed train are 0. 843 g and 0. 883 g,respectively,which agree with those of the fieldtest hunting wave of the bogie frame. The standard deviation σpof the bogie frame hunting wave is verified to be reasonable,and it can be provided as a good exciting source for lateral vibration analysis of the high-speed vehicle and track（ bridge） system.
