基于SIMULINK平台的渡槽结构隔震研究
|
摘要
【目的】建立基于SIMULINK平台的大型渡槽结构隔震的分析方法,以弥补目前大型渡槽结构隔震控制计算中存在的求解过程复杂等不足。【方法】基于MATLAB/SIMULINK仿真平台,建立了大型渡槽结构隔震分析的有限元动力计算模型,在模型中编制了动力仿真模块,利用铅芯橡胶支座对其进行减震控制。【结果】建立的大型渡槽结构隔震分析有限元动力仿真模型的运行过程简洁,模块移植性强,运算结果可靠,设置铅芯橡胶支座能够有效地抑制渡槽结构的地震响应。【结论】基于SIMULINK平台建立的隔震渡槽结构能有效地减震,这对大型渡槽结构的隔震响应分析具有一定的参考价值。
【Objective】 The isolation analysis method of large aqueduct structure was established based on the SIMULINK to compensate for the complicated process of the large aqueduct structure vibration isolation calculation.【Method】 The finite element model of isolated aqueduct was established based on the MATLAB/SIMULINK platform.A dynamic program was designed,and the lead rubber bearing was used to control the seismic response.【Result】 The isolation of large aqueduct structure finite element dynamic emulational model was simple,precise,and facile,with intuitional and believable results.Setting LRB can efficiently reduce the aqueduct responses to earthquake.【Conclution】 The built aqueduct structure can efficiently reduce seismic destruction.Results of the present study may serve as a base for seismic analysis of large-scale aqueducts.
