摘 要:换流阀组件作为柔性换流阀的核心部件,造价昂贵,其抗震性能直接关系到整个换流阀的抗震安全。文中运用地震模拟振动台试验的方法对某型号的真型换流阀组件开展了抗震性能研究。首先,为了更合理地布置测点,建立阀组件的有限元模型,通过数值模拟初步确定了阀组件的动力特性和抗震薄弱环节,为振动台试验中测点的布置提供依据;其次通过地震模拟振动台输入白噪声激励,测得了阀组件的频率、阻尼比动力特性参数;再次分别沿水平横向、纵向和竖向三方向输入5个正弦拍波以及人工地震波,测得阀组件的应变和加速度响应。最后根据振动台试验结果和试验后设备功能测试结果可以判定该型号阀组件可满足9度地震烈度地区的抗震强度要求。文中研究方法对类似设备的抗震性能考核试验具有重要的参考意义。As the core part of flexible converter valves,the converter valve assembly is expensive in construction and its seismic performance is directly related to the seismic safety of the complete converter valve system.In this paper,the method of seismic simulation shaking table test is used to study the seismic performance of certain type of real converter valve assembly.First,a finite element model of the valve assembly is set up to reasonably arrange the measurement points,the dynamic characteristics and weak seismic chain of the valve assembly is preliminarily defined through numerical simulation so to provide the base for the measurement point arrangement of the shaking table.Then,the white noise excitation is input through the seismic simulation platform to measure the frequency and damping ratio dynamic characteristic parameters of the valve assembly.After that,the strain and acceleration response of the valve assembly is measured by inputting 5 sinusoidal beat and artificial seismic wave along such three directions as lateral,longitudinal,and vertical directions to measure the strain and acceleration response of the valve assembly.Finally,it can be judged in accordance with the test result of the shaking table and the function test result of the equipment after test that this type of valve assembly of can meet the seismic requirement of the seis-mic area with seismic intensity at 9 degree.The method studied in this paper has important reference for the check of similar seismic performance of similar equipment.
