Usually, automobile brake and power steering hoses have been developed through investigating several actual prototype hoses experimentally. Recently, high durability has been required for brake hose because periodic renewing has not been requested anymore for personal automobiles. In this study, FEM stress analysis has been applied to the crimped portion of hydraulic brake hose in order to promote developing the automobile hoses more efficiently. It is found that the large normal stress σn, which may control the sealing performance, appears at the crimped portion between the nipple and inner rubber. The results suggest that several grooves putting at the surface of nipple are effective for causing large σn, which may improve the sealing performance and hose lifetime. The effect of compression set of the rubber on the sealing performance is investigated, and the lifetime of hydraulic brake hose is estimated form the maximum stress appearing at the groove on the nipple.
