摘　　要：利用动力学软件SIMPACK建立了具有二系横向和垂向半主动悬挂自导向式摆式客车动力学模型。介绍了PID半主动控制原理和控制策略,阐述了摆式客车模型建立方法。将半主动悬挂与被动悬挂在平稳性上进行对比分析,分析主要包括车体横向加速度、平稳性指标、横向振动幅频特性、前后摆枕和前后构架加速度均方根值、轮轨横向力。分析结果表明,采用PID半主动悬挂装置能有效的提高摆式客车的运行平稳性,同时也给摆枕、构架和轮对的动力学性能带来了负面影响,但其效应较小。综合考虑,能突显此控制方式的优越性,对进一步改善摆式客车运行品质具有重要的工程意义。Established a lateral and vertical semi - active secondary suspension tilting train model with self- steering radial bogies via dynamics simulation software SIMPACK. The PID control principle was introduced. The building method of the tilting train model was exposed. Compared with the passive suspension tilting train in analyzing its ride stability, which primarily includes carbody lateral acceleration, ride stability indices, lateral vibration amplitude- frequency characteristic, acceleration RMS of back- forth bolster and frame, attack angle of wheelsets. The analytic results show that the PID semi - active devices effectively raise the ride stability of tilting trains. Meantime, it took negative impacts on dynamics of the bolsters, frames and wheelsets. But the effect is minor in some measure. Considering synthetically, this can demonstrate its superiority in control and it has the momentous project designation to further improve the running quality of tilting trains.
