摘要
利用SIMPACK软件建立某高速动车组(包括2节动车和1节拖车)的纵向、垂向、横向耦合动力学模型,在模拟高速运行并考虑基本气动力的作用下,探讨了高速动车组车间纵向、垂向、横向减振器对动车组运行平稳性指标及振动加速度、曲线通过安全性能的影响。计算结果表明,安装车间减振器对高速动车组的动力学性能具有一定的改善作用。
The longitudinal,vertical and lateral coupling dynamics model for a certain type of multiple units(including 2 motor cars and one trailer) is set up with the SIMPACK software.With simulation of high speed operation and consideration of basic aerodynamics,the effects of longitudinal,vertical and lateral dampers between vehicles in high speed multiple units on the ride comfort indexes and acceleration,negotiation safety performance of the multiple units are discussed.The calculation result shows that installation of dampers between vehicles can make certain improvement on the dynamics performance of high speed multiple units.
