Study on Seismic Performance Shaking Table Test of Real Converter Valve Assembly
摘要
Abstract
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.关键词
