response analysis program

Seismic time-history response behavior analysis of long-span bridges are analyze by using the modules developed with the program ANSYS.

用有限元程序ANSYS建立了有限元模型，并模地震反应.基于ANSYS的大跨桥梁抗震分析计算模块对桥梁结构进行地震加速度时程响应分析。

The program, which is coded in C, puts time and frequency domain analysis, graph display and plotting together into one integral unit, capable of analyzing and studying any kinds of partial response.

该程序用C语言编程，将时域一频域分析、绘图、打印结合为一体，可对各种类型的部分响应进行分析研究。

The analysis program is compiled in this thesis and the dynamic response of high-speed railway vehicle-bridge coupling system is studied. Firstly, for the vehicle subsystem, a space vibration analysis model constituting of such rigid bodies as carriage, bogie frame and wheel is built.

编制了计算程序，并研究了高速铁路车桥耦合系统的动力响应。首先，针对车辆子系统，将车体、转向架、轮对简化为刚体，建立了车辆空间振动分析模型。
