摘　　要：以采用单轴转向架的悬挂式单轨车辆为研究对象,利用UM软件建立其动力学模型,分析不同轨道不平顺波长对车辆动力学性能的影响。结果表明:对于运营速度为50 km/h的车辆,直线运行时,轨道垂向不平顺敏感波长范围为3~10 m,轨道横向不平顺敏感波长范围为6~20 m;曲线运行时,轨道垂向和横向不平顺敏感波长范围均为10~20 m。Taking a suspended monorail vehicle with single-axle bogies as the research object,its dynamic model is established by UM software,and the influence of different track irregularity wavelengths on vehicle dynamic performance is analyzed.The results show that,for the vehicle with an operating speed of 50 km/h,the sensitive wavelength range of track vertical irregularity is 3~10 m,and the sensitive wavelength range of track lateral irregularity is 6~20 m when running on the straight section.When running on the curve section,the sensitive wavelength range of track vertical and lateral irregularity is 10~20 m.
