Abstract
Notice of Retraction
After careful and considered review of the content of this paper by a duly constituted expert committee, this paper has been found to be in violation of IEEE´s Publication Principles.
We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper.
The presenting author of this paper has the option to appeal this decision by contacting TPII@ieee.org.
The product which characterizes fatigue induced failure always suffers complex fatigue loads, and the damage caused by fatigue loads accumulate with time. Besides, the existence of shocks can not only increase the risk of failure directly, but also affect the magnitude of damage caused by fatigue loads. This paper analyzes the reliability of products when fatigue loads and shocks are involved at the same time. The features of fatigue damage and shock damage are investigated, and the coupling relationship between them is discussed. With assumptions of HCF and low-energy shocks, the effect of shocks on the fatigue damage is characterized as the degradation of the ultimate strength of the product. The overall reliability model with fatigue failure and shock failure is developed. Two conditions are considered for the reliability model: shocks with fixed time period and shocks with HPP. Three important cumulative damage theories are adopted. An engineering case of actuator cylinder is given to demonstrate this proposed approach.
