摘要:为了研究中速磁浮受流器在160~200 km/h速度等级下的运行状态,使用SIMPACK软件建立自由度为134的新型中速磁浮车辆动力学模型,计算得到160 km/h、180 km/h、200 km/h三种速度工况下的车辆右前侧受流器安装位置振动响应。将振动响应作为外部激励导入受流器-供电轨(靴轨)动力学模型,分别计算出三种速度下,静态接触力预设为120 N、130 N、130 N、140 N、140 N、150 N时受流器滑靴与供电轨间的动态接触力。结果表明,要使受流器在该速度工况下均能稳定工作,静态接触力预设值应分别不低于130 N、140 N、150 N。

Abstract:In order to study the operating status of the medium speed maglev current collector at 160~200 km/h speed grades, a new type of medium speed maglev vehicle dynamic model with 134 degrees of freedom was established by using SIMPACK software. The vibration response of the installation position of the right front current collector was calculated respectively at 160 km/h, 180km/h and 200 km/h. The vibration response was then imported as an external excitation into the current collector-power rail (shoe-gear rail) dynamic model, and the static contact force was preset to 120 N, 130 N, 130 N, 140 N, 140 N, 150 N at the three speeds. The results showed that in order to have the current collector work stably at this speed, the preset static contact force should not be less than 130 N, 140 N, and 150 N respectively.
