Handbook of Reliability Prediction Procedures for Mechanical Equipment

摘要

A reliability prediction is performed in the early stages of a developmentprogram to support the design process. Performing a reliability prediction provides for visibility of reliability requirements in the early development phase and an awareness of potential degradation of the equipment during its life cycle. As a result of performing a reliability prediction, equipment designs can be improved, costly over-designs prevented and development testing time optimized. Performance of a reliability prediction for electronic equipment is well supported by standardized documentation in the form of military standards, specifications and handbooks. Such documents as MIL-STD-756 and MIL-HDBK-217 have been developed for predicting the reliability of electronic equipment. Development of these documents was made possible because the standardization and mass production of electronic parts has permitted the creation of valid failure rate data banks for high population electronic devices. Such extensive sources of quality and reliability information can be used directly to predict operational reliability while the electronic design is still on the drawing board.
