摘要
应用大型通用有限元程序ANSYS建立了某大型冲击电压发生器塔架结构体系的有限元计算模型,进行了抗震抗风性能分析.通过数值计算,讨论了输入不同地震波对结构地震反应的影响,分析了力与位移(P-Δ)效应以及材料不同弹性模量对结构反应的影响,计算结果可为电力设施的工程抗震提供一定的参考.
A structural system of large-scale shock voltage generator tower is first modeled using the finite element analysis software, i.e. ANSYSTM. Then, the anti-seismic and-wind analysis is conducted. Through numerical computations, the impacts of different seismic waves on structural seismic responses are discussed. In addition, such impacts as force and displacement （P-△） effects and material elastic modulus are analyzed on the structural responses. Finally, the computational results set a constructional anti-seismic reference for power facilities.
