Structured Method to Reconfigure the Fatigue Life of Products Such as HKS in a Refrigerator

To refine the product fatigue worked by machine such as automobile, refrigerator, etc., parametric Accelerated Life Testing (ALT) as a new reliability structured way puts forward to determine its design subjected to continual loads, entrenched on failure mechanism and design. It holds: (1) parametric ALT approach established on BX life, (2) load evaluation for elevated life experiment, (3) a smart, fitted, and well-cut sample of ALTs with changes, and (4) an appraisal of whether the system reaches the goal BX life. So, life-stress failure type with effort idea, accelerated factor, and sample size are suggested. This structured reliability way such as parametric ALT can help designer to discover the product flaws influencing reliability as calculated by the enhancement in life, L
B
, and the lowering in failure rate, λduring the design phase. As a result, manufacturers may avoid recalls from the market failure. As a test investigation, hinge kit system (HKS) in a household refrigerator was redesigned. After a tailored of parameter ALT, the HKS with design modifications were anticipated to realize the life objective - B1 life ten years.
