摘要
利用SIMPACK多体动力学软件建立某高速动车组拖车模型,研究一系垂向减振器纵向、横向倾斜角度对该拖车模型非线性临界速度、直线轨道上的平稳性及曲线通过能力的影响。研究结果表明:一系垂向减振器倾斜角度对车辆稳定性和平稳性影响较大,对曲线通过性能影响较小。
In this paper,the influence of the primary vertical damper tilt angle on vehicle＇s nonlinear critical speed,riding index on straight track and the ability to curve passing were analyzed through establishing a high-speed EMU trailer model in SIMPACK.The results show that the primary vertical damper tilt angle greatly affects the vehicle stability and running behavior,and have less impact on the performance of curve passing.
