Abstract :
The results of this work provide design guidance for critical appliance components, allows the designer to assess impact of design changes on reliability early in the design phase, aids in FMEA execution and risk assessments and is a valuable accelerated test planning tool. The generic method of constructing these studies, which is presented here, can be applied to any component for any industry. This work provides relationships for failure rates for each component as a function of its respective mechanisms, acceleration factors and parameters. It describes the generic approach as to how these relationships were developed; how the relationships are made available to the design teams and how they are used. This Mechanical Life Prediction Database is under continuous improvement as new components are introduced, or new failure modes, models or mechanisms are discovered
