Double-Crossed Step-Stress Accelerated Life Testing for Pneumatic Cylinder

摘要：

　　This paper discusses the principle and method of Double-Crossed Step-Down-Stress Accelerated Life Testing (DCSDS-ALT) for pneumatic cylinders.As to pneumatic cylinder,the step-down-stress testing failure physics can be described as cumulative degradation model.Temperature and frequency are normally chosen as the test stresses.The failure data obtained under DCSDS-ALT testing steps can be converted to those under constant stress testing.And the reliability specifications can be derived accordingly.To compare Double-stress ALTs with traditional constant stress testing shows Double-stress ALTs can meet the accuracy demand.The 5% of average lifetime estimation error and 1.85% of the characteristic lifetime error are very satisfying for pneumatic industrial lifetime prediction.
