A Study on Acceleration Factor and Acceleration Coefficient Determination by Analyzing Brake Failure Data

브레이크 고장데이터 분석을 통한 가속인자 및 가속계수 결정에 관한 연구

Purpose: Fault data on automobile brakes are applied to reliability and statistical analysis methods to derive the brake acceleration factor and acceleration factor for automobiles. Based on these results, a brake acceleration life test design is proposed.Methods: The factors influencing brake failure are derived from literature review. The wear data are extracted by two-mixture Weibull distribution analysis based on three levels of failure data to determine if the factor affects the failure of brake parts. The extracted wear data are analyzed to confirm the acceleration and determine the acceleration factor and the acceleration factor.Results: Acceleration life tests can be designed from existing vehicle brake life tests by reflecting the derived acceleration factors and acceleration factors.Conclusion: With the reduction in the proposed testing time compared with the existing one, a more reliable design can be achieved. The proposed analytical process can be useful in deriving the acceleration factor for the design of an accelerated life test for non-brake car parts
