Abstract

Heavy commercial vehicles, which used for construction works, mostly have drum brakes. There are three types of drum brakes named S cam brakes, Z cam brakes and Wedge brakes, which are safety related components for operation of the vehicle. Fatigue life of brake components is critical. One of the most important component is lever which transfers actuation force to camshaft. In this study, spot face geometry of the lever was examined. FEA model multilinear material model was prepared using ANSYS. Two types of specimens were analyzed by static structural FEM under load of 15 kN. Effects of this three-dimensional stress analysis on fatigue life compared experimentally. All the experimental results were plotted and explained by using Weibull Analysis which is one of the widely used lifetime distributions in reliability engineering.
