【摘要】 运用PRO/E对母线槽钢结构支架进行三维建模,通过ANSYS软件对支架进行模态分析,从而求解出支架的模态参数,得到支架的固有频率和振型特征,并进行了地震反应谱分析,为进一步研究支架动力学特性以及支架的优化设计提供参考依据。更多还原

【Abstract】 The three-dimensional model of the steel structure support of bus ducts is built by PRO/E,and modal analysis is conducted on the steel structure support through the software of ANSYS so as to identify the modal parameters of the steel support,the natural frequency and vibration features.According to model analysis,seismic response spectrum analysis is conducted for the steel structure support.All of these will lay the foundation for the further research on the dynamics characteristics of the steel structure support and provide the reference for the steel structure support optimization design.更多还原
