Abstract Many signature analysis techniques have been developed for detecting bearing damage. In this paper, a number of these techniques are evaluated and their abilities to detect the existence and progression of damage are quantitatively compared. Needle bearings are used for this evaluation because they are noisier than ball bearings, and there has been little published regarding their vibration behavior. The signature analysis techniques are evaluated using three increasing levels of outer race damage. The Evaluation criteria are based on the ability of a technique to repeatedly detect a damaged bearing and to correctly indicate the progression of damage level.

Process Method

A reconfigurable product serves as multiple products to deliver different functions through reconfiguration processes to change between product configurations. An optimization method was developed in our previous research to identify both the optimal design and the optimal reconfiguration processes. Because the generic design or process considering different candidates was modeled by an AND–OR tree or graph, importance weights were assigned to nodes with an AND or OR relation, such that the less-important nodes were pruned to improve the optimization efficiency. In this research, an extended analytic network process method is introduced to further improve the quality of the optimal reconfigurable product design approach when dependency relations among descriptions of design/process candidates and evaluation criteria are considered. In this method, the initial weights of the design/process nodes in the AND–OR tree or graph are adjusted based on the dependency relations such that the weights which truly reflect their contributions to the solutions are achieved. In addition, multiple evaluation criteria similar to the evaluation measures used in optimization are selected to identify the weights of the design/process nodes. A case study has been implemented to demonstrate effectiveness of the extended analytic network process for improving the quality of optimal reconfigurable product design.

to achieve standardized design of industrialized notoginseng seedling slot, this paper is based on analyzing existing seedling slot to propose a total of six kinds of design schemes which are combining structure and size. Then four evaluation criteria are constructed that consist of land-use ratio, mechanical operation stability, economic rationality and manual operation convenience. At last, Scheme optimization is using analytic hierarchy process (AHP), the best scheme is found

The article describes the application of AE technique in control and evaluation of the pipe overstraining process. The trials of overstraining were conducted according to a programme of pipe loading with internal pressure, developed and adjusted to the examined pipe material. In the studies two systems of acoustic emission were used, viz. PAC Mistras 2001 and Vallen AMSY. The procedure adopted in the development of evaluation criteria based on an analysis of the recorded acoustic events was described. Next, the criteria of evaluation were presented. The effectiveness of the applied method, the validity of the adopted criteria, and the consistency of the obtained quantitative results were checked during tests performed by other NDT methods. A comparative analysis was made to serve as a complementary tool in final evaluation of the pipe overstraining process done by AE technique.
