Comments on Oil Seals for Gas Pressurized Shock Absorbers of Automotive Suspensions

Development and verification of a shock absorber and its shim valve model based on the force method principles

“…Based on the literature [6,8,28], deformations of the valve shims are solved by choosing relevant algorithms from Roark's formulas for stress and strain described in the literature [27].…”

“…However, the problems dealt with by the author are not related to the structure of the valves [18,19], and discrepancies, which were explained by the ignorance of physical properties of the oil (Oil Bulk modulus), were noticed during the model validation. The influence of the technical condition of structural elements of the shock absorber on its exploitation and damping characteristics is examined in literature [2,3,4,11,13,28] as well. It can be seen from the provided examples that various research works, where the influence of the structure of a shock absorber on its damping characteristics is discussed, are published; however, in such works, including the reviewed ones, seeking to simplify the process of modelling, various simplifications are made and they predetermine inexact results of modelling or the models becomes too complicated and not ready for practical application.…”
