RESUMO

This work presents a methodology for reliability analysis of automotive pneumatic brakes, with the objective of providing the designers and the brake systems analysts with some tools which can facilitate the incorporation of the reliabilty variables in the design of the components, the subsystems and the brake systems, in project s realtime. The Weibull distribution is used as a function representing the failure events, calculating the reliability, the unreliability , hazard rate and failure density function, of the components of the brake circuits. The analysis method is composed of five steps: physical model, systems identification, reliabilitymodel, mathematical mode! and computational model. In the computational model it was developed the BRAKEREL program (Brake Reliability Program) using the Visual Basic for Windows in calculating the reliability, the unreliability, hazard rate and the failure density function, for alI the components of the system. The results are presented in grafical form and tables
