Szukana fraza: [Abstract = "However, if the numerical results have confirmed the slight effect of the grooved lip on the rotary lip seal performances, it seems relevant to investigate the influence of such grooves on the reciprocating hydraulic rod seal behavior. Thus, the scope of this work is to perform a parametric study of the grooved lip throughout a one\-dimensional elastohydrodynamic model by taking into account the elasticity of the lip and the shaft roughness."]
