| Summary: | The article considers the influence of different tolerance values on the stiffness of elastic rings in squeeze film dampers. This type of damper is widely used in gas turbine engine supports. The available analytical solutions have a number of limitations. A parametric finite-element model of an elastic ring, a set of two interconnected elastic rings and a simplified segment is presented. The results obtained show the discrepancy between values of compliance for different numerical models as compared to analytical approaches. The effect of assembly tolerances on the value of compliance is shown. |
