Abstract


Power facilities is an important part of the lifeline engineering seismic study of the power facilities is one of the important research content of Lifeline Earthquake Engineering . Structural vibration control is an emerging technology , and made ??to flourish in recent years . Were shaking table test of utility boilers architecture model , different passive control method comparative analysis of boiler structure vibration control characteristics , last ANSYS finite element simulation and comparative analysis with the test results and the main content of this study : First introduction boiler structure Research and development of passive control technology . Secondly, the produced magnetic friction dampers , viscous dampers , viscoelastic dampers , and its hysteresis curve performance test . Third, shaking table test study of utility boilers architecture model . Through different combinations and position three damper mounted to the boiler structure test model to obtain the corresponding seismic response and compare the effect of different control scheme control . Summarizes the motion characteristics of the suspension system of the boiler structure and role of the original system Akira device . For the motion characteristics of the suspension system , the design the the viscous dampers boom install program . Based on ANSYS software , the establishment of the finite element model of the boiler structure test model of its earthquake response analysis and comparison with the test results , the results show that the reliability of the finite element model . Establish the three damper ANSYS finite element model , compared with the test results install the damper structure seismic response .
