Abstract: Faults in rolling element bearing are among the main causes of breakdown in rotating machines. Vibration is an effective technique for machine condition monitoring. Vibration signals from a defective bearing with a localized fault contain a series of impulsive responses, which result from the impacts of the defective part(s) with other elements. Most researches carried out have focused on fault location identification. However, limited work has been reported for fault severity estimation, which is critical to make decision for maintenance actions. To improve current diagnostic capability, this paper pays more attention to bearing fault severity diagnosis. It models the vibration sources from bearing defects as an impact process with constant size but three different lengths corresponding to outer race fault, inner race fault and roller fault, respectively. Then an experimental study was followed to evaluate this model. Moreover, the conventional envelope analysis of the measured vibrat

Abstract: This study highlights and proposed the integration framework between Kansei Engineering (KE) and Kano Method (KM) in the product development. Kansei Engineering (KE) used is related to emotional needs of consumers of a product, while Kano Method (KM) is the articulation of the quality attributes of product. Through the survey conducted using the questionnaires developed of 6 Kansei Words (i.e. Miserable-Comfortable(MC), Slippery-Firm (SF), Irritating-Convenience (IC), Boring-Attractive (BA), Simple- Stylish (SS), and Ugly-Beautiful (UB)), the preference scale (between Dislike to Strongly Like), and 9 quality attributes basedFunctional vs. Dysfunctional questions, we use the design of pen product as a case study to justify the integration framework proposed. The survey is distributed to 220 students in higher education public institutions in Melaka, Malaysia. In this study, the result showed that any correlation existed between the emotional design (KE) and quality attributes (KM). Howe
