Abstract
Three-dimensional solid modeling and structural design of the simulation turntable damper were carried out by three-dimensional software, and the intensity checking of the main parts of the damper was carried out by finite element software. The tests of the damper samples were carried out, and the electro-hydraulic servo MTS fatigue test rig was used to test the dynamic characteristics of the two dampers, and the dynamic stiffness values of the dampers at different frequencies were obtained. The test results show that the dynamic stiffness values of the two damper samples are 5282N/mm and 4356N/mm respectively, which are basically consistent with the design values; due to the production variability, the dynamic stiffness values of the two damper samples have some differences; the dynamic stiffness values of the damper samples increase slightly with the increase of the loading frequency. The dynamic characteristics of the dampers were obtained through the tests, and it was verified that the structure and performance of the simulation turntable damper met the design requirements.
