STUDY ON VIBRATION RESPONSE OF AIR COOLED CONDENSER PLATFORM UNDER THE EXCITATION OF LARGE-DIAMETER FANS IN THERMAL POWER PLANTS

摘要：

A 1/8 scale air cooled condenser platform model is constructed and tested to study the vibration response under the excitation of large-diameter fans. The structural dynamic properties, the amplitude-frequency curve under different rotation speed and work state of fans, and the dynamic strain of structural members are measured in the experiment. A harmonic response analysis is done with ANSYS(R) , and the calculation results show agreement with the test results.Some design advice is presented based on the experiment results and FEM analysis.
