Abstract :
Acceleration factor (AF) is important to determine the proper test time for accelerated life test (ALT). This paper presents the method for determining AF to be used in ALT through duty analysis together with usage profile and field failure data. Usage profile is obtained through surveys from farmers using questionnaires, interviews and field visits. Field failure data is gathered from authorized service centers around South Korea. A case study of tractor transmission is shown with the proposed method.
