Reliability prediction procedures for mechanical components at the design stage

Abstract

This paper reports progress towards the development of procedures and techniques for assessing the reliability of components at the design stage. From a fundamental understanding of the degradation and failure processes and their relation to the underlying operational, environmental, materials and design variables, the paper develops procedures to support reliability prediction of mechanical devices using an electromechanical actuator as a case study. The methodology is illustrated by particular reference to the process of sliding wear leading to jamming of the actuator.

Development and application of equipment maintenance and safety integrity management system

“…Paul and Funkhouser (2007) studied equipment integrity and risk analysis for refineries and chemical plants. Warburton, Strutt, and Allsop (1998) presented a methodology for predicting characteristics of mechanical-failures. Martorell et al (1999) researched the utilization of maintenance indicators that can evaluate the performance of NPP and the effectiveness of maintenance programs.…”

“…Petrochemical, chemical, refining, petroleum and other process industrial plants are trying to implement risk-based maintenance programs to improve safety, reliability and availability of the plants (Warburton et al, 1998). RAM is one of the risk evaluation models that are applied in MSI.…”

“…heavily depends on the accuracy of the probabilistic models and reliability data. Equipment failure may impact productivity and gross profit (Warburton et al,1998), which makes engineering solutions to expense reduction, reliability enhancement and customer requirement satisfaction very important (Barringer, 2000).…”

Reliability, availability and maintainability analysis in food production lines: a review

“…Higher plant reliability reduces equipment failure costs. Failure decreases production and limits gross profits (Warburton et al ., 1998). Barabady & Kumar (2008) reported that system reliability, maintainability and availability have assumed great significance in recent years because of competitive environments and overall operating/production costs; an unplanned failure can result in significantly higher repair costs than a planned maintenance or repair.…”

Practical reliability-based analysis of a coil tube spring

“…As with many reliability-critical mechanical components, a numerical method needs to be introduced to enable reliability analysis of a coil tube spring. D uring the last three decades, there has been considerable research activity about reliability-based analysis of mechanical components, in the area of engineering research, as described in a number of monographs [1][2][3][4][5] and papers [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24]. This paper focuses on the probabilistic perturbation method for reliabilitybased analysis.…”
