27 Required function (mission profile) • Set up the reliability block diagram FMEA where (RBD), by performing a redundancy appears Eliminate reliability weaknesses • Determine the component stresses • component/material selection • Compute the failure rate Ai of each • derating component • screening • Compute R(t) at the assembly level • redundancy • Check the fulfillment of reliability design rules • Perform a preliminary design review no yes Go to the next assembly or to the next integration level Figure 2. 1 Reliability analysis procedure at assembly level Taking account of the above considerations, Fig. 2. 1 shows the reliability analysis procedure used in practical a...
High reliability, maintainability, and safety are expected from complex equipment and systems. To build these characteristics into an item, failure rate and failure mode analyses have to be performed early in the design phase, starting at the com ponent level, and have to be supported by a set of design guidelines for reliability and maintainability as well as by extensive design reviews. Before production, qualification tests of prototypes must ensure that quality and reliability targets have been reached. In the production phase, processes and procedures have to be selec ted and monitored to assure the required quality level. For many systems, availabi lity requirements must also be satisf...
Reliability engineering is a rapidly evolving discipline, whose purpose is to develop methods and tools to predict, evaluate, and demonstrate reliability, maintainability, and availability of components, equipment, and systems, as well as to support development and production engineers in building in reliability and maintainability. To be cost and time effective, reliability engineering has to be coordinated with quality assurance activities, in agreement with Total Quality Management (TQM) and Concurrent Engineering efforts. To build in reliability and maintainability into complex equipment or systems, failure rate and failure mode analyses have to be performed early in the development phas...
