Long-term vibration of the saturable reactor may lead to loosening

thereby posing a threat to the normal operation of converter valves. Understanding and mastering the vibration characteristics is essential to mitigating potential safety hazards. Therefore

the vibration characteristics of a saturable reactor which has been put into operation and its simulation calculation method are studied in this paper. Firstly

a full-scale model is established

and magnetic-solid mechanic coupling simulation is conducted under normal working conditions. Loose conditions are then calculated by adjusting Young's modulus of the core. Secondly

vibration tests are carried out on a vibration testing platform under both normal and loose conditions. Thirdly

the experimental data and simulation results are analyzed and compared. The results indicate that there is less than 8% error in peak vibration acceleration between the simulation and experiment results

demonstrating that the model effectively simulates vibration characteristics under different states. The research methodology presented in this paper can serve as a foundation for the subsequent vibration simulation of the converter valve layer and valve tower.
