| 摘 要： | 建立了某高速列车车体有限元模型,采用Guyan缩减进行模态求解,结合SIMPACK多体动力学软件建立包含弹性车体的系统动力学模型。运用模型分析了车体弹性模态对运行平稳性的影响,研究了弹性车体与转向架构架垂向耦合振动。分析结果表明：当车体垂向一阶弯曲频率与车体点头振动空响应点频率接近时,会发生车体的垂向弹性共振;当车体菱...

| Abstract: | A finite element model of car body for a high-speed train was built,and the modal parameters were calculated by using Guyan reduction method.A system dynamics model including flexible car body was established by using multi-body dynamics software SIMPACK.The influence of car body elastic mode on riding quality was analyzed based on the model,and the vertical coupled vibration between flexible car body and bogie frame was studied.Analysis result shows that when the first vertical bending frequency of car bod... |
