摘　　要：以一柔性直换流阀为研究对象,进行了铅芯橡胶隔震支座(LRB)基础隔震设计,通过ANSYS有限元模拟得到隔震前后结构的动力响应,对比分析了LRB隔震性能,结果显示:该柔性直流换流阀LRB隔震方案隔震性能优异,可显著降低震中换流阀结构应力和加速度响应,提高柔性直流换流阀结构的安全性。This paper focuses on a specific flexible DC converter valve and explores the design of a Lead-Rubber Bearing(LRB)foundation isolation structure.Through finite element simulations using ANSYS,the dynamic responses of the structure before and after isolation are obtained.A comparative analysis of the LRB foundation isolation performance is conducted.The results demonstrate that the LRB isolation scheme for this flexible DC converter valve exhibits exceptional isolation performance.It significantly reduces the stresses and acceleration responses in the structure during seismic events.This isolation design significantly enhances the safety of the flexible DC converter valve structure.
