Since the strength of a brake shoe is affected by the magnitude and distribution shape of the contact pressure with the drum, the contact pressure between the shoe friction material and drum was calculated using a 2-Dimensional non-line ar contact analysis in a state. And the brake was actuated by i nput air pressure and the drum of it was calculated both stationary and dynamic b ased on forced torque applied to the drum during the static sta te analysis. The results of the above analysis were then used as the load bounda ry conditions for a 3-Dimensional shoe model analysis to determ ine the maximum strain on the shoes. In the analysis model, the values of tensi le test were used for the material properties of the brake shoe s and drum, while the values of compression test were used for the friction material. We assumed it as linear variation, even though the properties of friction material were actually non-linear. The experiments were carried out unde r the same analysis conditions used for fatigue test and under the same brake system which equipped with a brake drum based on the actual axle state in a vehicle. The strains were measured at the same loc ations where the analysis was performed on the shoes. The obtained results of th e experiment matched well with those from the analysis. Consequ ently, the model used in this study was able to determine the stress at the maxi mum air pressure at the braking system, thereby a modified shoe model in facilitating was satisfied with the required endurance strength in the vehicle.교신저자 서창민: 대구광역시 북구 산격동 1370, 053-950-5573, cmsuh@knu.ac.kr" @default.
