| 摘 要： | 针对TR08高速磁浮车辆运行中铝合金悬浮架弹性变形较大的问题,采用ANSYS建立了悬浮架有限元模型,并进行结构模态分析;为了提高悬浮架动力学数值计算效率,依据等效变形原则建立刚性悬浮架模型,计算等效弹簧参数.基于弹性和刚性悬浮架建立磁浮车辆整车动力学模型,对比分析了曲线通过时2种悬浮架模型动力学响应.计算结果表明:车辆以速度100,250和430 km/h通过半径为2 260m的曲线时,2种悬浮架模型铰点垂向位移计算值之差不超过0.5mm,悬浮间隙计算相对误差小于2%,悬浮架扭转角响应曲线基本重合,表明建立的等效刚性悬浮架模型是合理的;应用于整车动力学性能仿真时具有足够的计算精度,其计算效率远高于采用弹性模型时的计算效率,但弹性悬浮架模型能更准确、全面地模拟其弹性变形和振动响应.

| Abstract: | In order to calculate elastic deformations of the levitation chassis of TR08 maglev vehicle,a finite element model of the levitation chassis was established using ANSYS software,and modal analysis was carried out.The equivalent rigid model of the levitation chassis was also developed to improve calculation efficiency,and the equivalent spring parameters were calculated according to the same deformation principle.Thus two kinds of maglev vehicle models using the elastic or rigid levitation chassis were devel... |
