Systematic Methods to Enhance the Life of Mechanical System Such as Compressor Subjected to Repetitive Impact Load

Abstract

To improve the life of mechanical product, parametric Accelerated Life Testing (ALT) as reliability methodology proposes to assess the design of mechanical products subjected to repeated loads, based on (generalized) life-stress formulation and sample size equation. It will help an engineer to reveal the design defects of the mechanical product which making a critical influence on product reliability for the design procedure. Eventually, companies can circumvent product recalls due to the design flaws from the marketplace. As an experiment example, the redesign of compressor in a domestic refrigerator was studied.
