An exploratory study for predicting component reliability with new load conditions

Zhengwei HU, Xiaoping DU

Frontiers of Mechanical Engineering 2019, Volume 14, Issue 1,   Pages 76-84 doi: 10.1007/s11465-018-0522-x

Abstract: Reliability is important to design innovation. A new product should be not only innovative, but also reliable. For many existing components used in the new product, their reliability will change because the applied Loads are different from the ones for which the components are originally designed and manufactured. Then the new reliability must be re-evaluated. The system designers of the new product, however, may not have enough information to perform this task. With a beam problem as a case study, this study explores a feasible way to re-evaluate the component reliability with new Loads given the following information: The original reliability of the component with respect to the component Loads and the distributions of the new component Loads. Physics-based methods are employed to build the equivalent component limit-state function that can predict the component failure under the new Loads. Since the information is limited, the re-evaluated component reliability is given by its maximum and minimum values. The case study shows that good accuracy can be obtained even though the new reliability is provided with the aforementioned interval.

Frontiers of Mechanical Engineering 2013, Volume 8, Issue 1,   Pages 88-94 doi: 10.1007/s11465-013-0361-8

Abstract:

Planetary gearboxes operate usually in non-stationary conditions generated mainly by variable loadsgearboxes in such conditions, a mathematic model is developed including driving unit, transmission and loadThe variability of load induces a variable speed of the transmission which is taken into account whencomputation of the dynamic response shows an intimate relation between the vibration amplitude level and the loadAs the load increase the vibration level increase.
