Establishment and Validation of Finite Element Model of Seismic Action for Interconnected UHV Equipment in Substation
摘要
Abstract
To build a seismic finite element model of the interconnected UHV equipment,the characteristic parameters of restoring force of the sliding fittings for hard bus and the bit-shaped function of flexible bus considering stiffness,must be determined.In this study,quasi-static test was conducted to obtain the restoring force parameters of the sliding fittings,such as the sliding force,the sliding stiffness,and the additional damping ratio.And the bit-shaped function considering the stiffness of flexible bus was deduced via mechanical analysis.Thus,a seismic finite element model of the interconnected UHV equipment was established.Finite element analysis shows that the calculation results of the interconnected UHV equipment are very close to the test data of shaking table,which validates the correctness of the finite element model.This study may provide theoretical and experimental foundation for establishing finite element model of interconnected UHV equipment.关键词
