Paper Title:
FEM Analysis for Sealing Performance of Hydraulic Pressure Brake Hose Caulking Portion
  Abstract

Usually, development of automobile brake hose and power steering hose has been realized through evaluating several actual prototype hoses experimentally. Recently, high durability and high development effect for brake hose has been required because periodic exchange for the brake hose has not been requested any more. In this study, therefore, stress analysis by FEM is performed to the crimped portion of hydraulic pressure brake hose in order to promote the development of the automobile hoses more efficiently. It is found that large normal stresses σr in the radial direction appear at the crimped portion between the nipple and inner rubber. The results suggest that several grooves on the nipple surface may be useful because they cause large σr, which may improve the sealing performance. The effect of permanent deformation of the rubber on the sealing performance is discussed by assuming initial deformation of the rubber at the crimped portion.
