摘要:建立了100%低地板轻轨车辆动力学模型,分析了车间纵向减振器阻尼参数对低地板车辆的稳定性、平稳性和曲线通过性能的影响,结果表明阻尼设置对车辆的直线运行性能和曲线通过存在不同影响。因此,低地板车辆应采用具有大小二级阻尼的半主动减振器,直线行驶时采用大阻尼以保证车辆的稳定性和平稳性;曲线通过时采用小阻尼以提高车辆曲线通过性能。可通过检测车体和转向架的相对摇头角,来判断车辆是运行在直线上还是曲线上。

Abstract:Through establishment of a100%low-floor light rail dynamics model, having an analysis of the longitudinal damping parameters for low-floor vehicle stability, stationarity and curve-passing dynamics. The results show that the damping parameters have different effects on straight performance and curve-passing dynamics. Thus, low-floor vehicles should be equipped with semi-actived amper with two damping parameters. Using a larger damping ensure the stability and stationarity when on straight. Using a smaller damping ensure the curve-passing dynamics when passing curve. By detecting relative yaw angle between the body and bogieto judge the vehicle is running on a straight line or curve.
Key words:low-floor rail vehicle;semi-active damper;longitudinal damper;stability;stationarityand curve-passing dynamics
