摘要:
考虑轨道不平顺因素，提出了一种基于UM仿真软件的高速磁浮列车轨道不平顺动力学研究策略。首先，实况下测量当磁浮列车的运行速度为300 km/h和430 km/h时，左右测点的不平顺变化幅值范围及其增加量值。然后，通过将轨道不平顺谱导入UM软件，并基于所搭建的高速磁浮列车模型，验证基于UM仿真模拟高速磁浮列车在此条线路运行的可行性。最后，将不平顺条件放宽至现有不平顺标准最大幅值(-4.3 mm，+3.8 mm)。通过仿真分析可知，当运行速度为430 km/h和500 km/h时，高速磁浮列车仍可安全运行。当运行速度为600 km/h，不平顺幅值增大为1.1倍和1.2倍时，高速磁浮列车仍可安全运行。但当不平顺幅值增大至1.3倍时，悬浮间隙最大值将超出下限值18 mm，导致高速磁浮列车不能安全运行。
Abstracts:
Considering track irregularity factor, a track irregularity dynamic research strategy based on UM simulation software for high-speed maglev train is proposed. Firstly, the range of irregularity change amplitude and the increase amount at the left and right measuring points are measured under real working condition with the maglev train of running speed at 300 km/h and 430 km/h. Then, the track irregularity spectrum is imported into UM. Through an established high-speed maglev train model, the feasibility of high-speed maglev train running on this line is simulated based on UM. Finally, the irregularity condition is extended to the current standard maximum amplitude (-4.3 mm, +3.8 mm). The simulation analysis shows that the high-speed maglev train can still run safely when the running speed is 430 km/h and 500 km/h. At a running speed of 600 km/h, the high-speed maglev train can run safely when irregularity amplitude is increased to be 1.1 and 1.2 times of the original value. When irregularity amplitude is increased to be 1.3 times, the maximum suspension gap value will exceed the lower limit by 18 mm, which causes the high-speed maglev train failing to run safely.
