... for the reliability analysis and design of the L-PBF process. The method determines a feasible region of the design space for given design requirements at specified reliability levels. If a design point falls into the feasible region, the design requirement will be satisfied with a probability higher or equal...

...Ming-Yi You; Lin Li; Guang Meng; Jun Ni Since pioneering work in 1972, the proportional hazard model (PHM) has been widely studied for survival analysis in the area of medicine. Recently, applying the PHM in the area of reliability engineering attracts significant research attentions. In this paper...

..., unnecessarily high costs can be incurred due to unexpected equipment failure (lack of maintenance) or excessive maintenance. In this paper, a reliability-based dynamic maintenance threshold (DMT) is calculated based on the updated equipment status. The benefits of the DMT are demonstrated in a numerical case...

... to constant BHF. Extensive research has been carried out in the past to determine this optimal profile. However, these deterministic efforts neglect the sensitivity of this optimal BHF design to unintended process variations inherent in sheet forming. This paper investigates the reliability of optimal...

... joining processes failure (mechanical) reliability An automotive body assembly process is a complex sheet metal joining process that involves a large number of parts and fixture stations. One of the major sources of dimensional variation is fixture-induced variation. A typical 3–2–1 locating...

...Hansun Ryou; Kwansoo Chung; Jeong-Whan Yoon; Chung-Souk Han; Jae Ryoun Youn; Tae Jin Kang In order to achieve reliable but cost-effective crash simulations of stamped parts, sheet-forming process effects were incorporated in simulations using the ideal forming theory mixed with the three...

... of fatigue life. Second, the time consuming and costly fatigue tests to obtain critical variance information for reliability design may be divided into less time consuming tests for obtaining variance information for individual variables contributing to fatigue variance. Based on the variance prediction tool...

...Theodor Freiheit; S. Jack Hu This paper analyzes the impact of machining parameter selection on machining system productivity. The method involves prediction of machine tool reliability from mechanical failure based on process choices and production rate. The machine reliability is then input...

...G. Lee; J. Mou; Y. Shen Inspection is commonly used to scrutinize the quality of manufactured products against established standards and specifications. However, the quality and reliability of many inspection processes are contaminated by various measurement errors. One of the prominent sources...
