Theoretical and experimental analysis of the physical behavior of gaskets in shock absorber

Abstract

The current study examines the theoretical and experimental behaviour of gaskets when using different cases of disc samples (free-free, free-fix and fix-fix). The samples are made of rubber. The deformation of the gasket as a function of loading depends significantly on how it is fixed to the rigid supports. Physical properties have been explained. In experimental analysis of the sample disc "Free-Free", the loading velocity does not have a significant influence on the range of values of the mentioned velocity. All the curves in the "Free-Fix" disc load illustrate that at the same deformation, the average pressure is higher than in the case of the "free-free" disc. At the deformation of 1.49 mm, the average pressure is 33% higher than all other graphs. In the case of the "Fix-Fix" disc, it is observed that the load, evaluated by the average pressure, is clearly higher than in the case "Free-Fix" disc. At a deformation of 1.49 mm, the average pressure was found to be 15 times higher.
