title = "Modelling and Experimental Verification of Stiffness Characteristics of Elastic Rings",
abstract = "A finite element model of the elastic ring in an Elastic Ring Squeeze Film Damper (ERSFD) was established, and the displacement boundary conditions of the elastic ring were derived based on its loading characteristics. The equivalent static stiffness of the elastic ring was then calculated. A test rig for verifying the vibration characteristics of the ERSFD was designed and built, and static stiffness tests were carried out. The results show that the finite element model of the elastic ring based on hexahedral elements can accurately calculate the stiffness characteristics of the elastic ring, with a relative error of 4.11\% between the theoretical results and experimental data. Due to friction effects, the stiffness characteristics of the elastic ring under cyclic loading exhibit significant nonlinear behaviour, and the force-displacement curve forms a hysteresis loop. The conclusions provide theoretical support for the subsequent construction of a fluid-structure interaction (FSI) model for ERSFD and offer guidance for the stiffness design of the elastic ring.",
