A THEORY FOR RAPID DETERMINATION OF RELIABILITY INDICES FOR MACHINE AND INSTRUMENT PARTS,

Abstract

Ordinary methods of testing machine and instrument parts for reliability are too time-consuming. A theory is developed for accelerating reliability tests which will give valid results. The theory is based on a distribution law and a hyperbolic law of service life. Samples are tested by step-wise loading until 50% of the objects fail. Meanwhile two other sample lots are tested under constant load. Results are manipulated mathematically to give reliability and service life indexes that can be extended to parts that have not been used. (Author)
