| 摘 要： | 运用有限元分析软件ANSYS建立轨道-地基-基础-偏心结构相互作用体系三维数值分析模型,分析在不同结构平扭比和不同列车运行速度情况下单层偏心结构的平扭耦联振动响应特性。分析结果表明:结构的平扭比对结构平扭耦联振动影响显著,随着平扭比的增大,平扭耦联振动响应有逐渐减小的趋势,而平扭比取值在1.0左右时,平扭耦联振动最为明显;车速对结构平扭耦联振动也有一定的影响,同一平扭比不同列车运行速度情况下,车速越大,振动越明显。

| Abstract: | Building track-foundation-eccentric structure interaction system three-dimensional numeri- cal analysis model by using finite element analysis software ANSYS. Analyzing translational-torsional coupling vibration response characteristics of single eccentric structure in case of different structural translational-torsional ratio as well as different train speed. The result shows that translational-torsion- al ratio had a significant influence to translational-torsional coupling vibration. It gradually decreased with the translational-torsional ratio increasing. And it got the maximum while the ratio value around 1.0. On the other hand, train speed had also a influence to translational-torsional couDlin~ vihration |
