System Life Prediction Approaches Based on Key Apparatus

摘要

Life parameter is important for product. It is very important for an engineer to predict system lifetime. Reasonable approaches of system life prediction can cause exact prediction of system life. One approach of system life prediction based on key apparatus is presented to solve the questions of absence of system life data and experiments of system life. By confirming the key apparatus of system which has influence on system life, analyzing life of key apparatus, and conducting accelerated experiments, life value estimated can be obtained. Then, life of system in all can be obtained by using method of accessory minimum life. The approach is valuable of applications and verified with experiments.
