摘　　要：采用ANSYS对脊骨梁的"肋梁-桥面板体系"进行了车桥耦合分析,考虑了车辆行驶速度和肋梁间距2个主要因素,运用限元瞬态动力时程分析的手段对其进行了动力学分析研究,得到了局部构件的冲击系数,提出了在对于此类桥梁进行设计时,应进行专门的动力学冲击效应分析,以确保其安全性。In this paper, ANSYS is used to analyze the dynamical coupling of vehicles and the deck slab structure, in which the vehicle speed and the distance between ribbing beams are mainly considered. The transient dynamic time history analysis of FEM is used and impacting coefficient about the local structure is got. It is suggested that the impact dynamics analysis is necessary in spine bridge desin to ensure structure safety.
