Abstract
The influence of geometrical factors on the variation of contact pressure at the inner edge of an approximately rectangular cross section dynamic sealing ring was studied using finite-element techniques. The possibility of varying the contact pressure distribution between the seal and the moving element was demonstrated and shown to be easier than for O-rings. An empirical formula is proposed which allows the calculation of curvature on maximum contact pressure. This permits the correction of results obtained by assuming conditions of plans deformation of the seal cross-section, and is particularly useful for the study of wear. (C.C.B.)
