摘要:
对横风激扰下的跨座式单轨车辆的运行平稳性进行分析.首先,分别采用瞬态中国帽风载模型和非定常随机风载模型模拟动态风场,建立跨座式单轨车辆动力学模型,并将两种风载模型作为外部激励分别施加到车辆上.其次,采取数值仿真方法,分析不同车速、风速、合成风向角的跨座式单轨车辆在横风作用时的动力响应.最后,对车辆运行平稳性进行评估,计算限值下的临界安全风速,得到横风激扰下跨座式单轨车辆运行的安全区域.结果表明:车速、风速和合成风向角对跨座式单轨车辆的运行平稳性有显著影响;当车速和风速过大时,车辆会发生失稳现象.
Abstract:
The running stability of a straddle monorail vehicle under crosswind disturbance was analyzed. First, the transient Chinese cap wind load model and the unsteady random wind load model were used to simulate the dynamic wind field, and a straddle monorail vehicle dynamic model was established. The two wind load models as external stimuli were applied to the vehicle, respectively. Second, a numerical simulation method was adopted to analyze the dynamic response of a straddle monorail vehicle under the action of crosswind with different vehicle speeds, different wind speeds, and different synthetic wind direction angles. Finally, the vehicle’s running stability was evaluated, the critical safe wind speed under the limit was calculated, and the safety area of straddle monorail vehicle operation under crosswind disturbance was obtained. The results show that the vehicle speed, wind speed and synthetic wind direction angles have a significant impact on the running smoothness of the straddle monorail vehicle. When the vehicle speed and wind speed are too large, the vehicle may experience instability.
