A New Reliability Methodology for the Validation of Mechatronic Systems

摘要

The purpose of this article is to propose an innovative methodology helping in the decision if a precipitated failure during HALT is relevant (or not) to a Design change. The methodology is based on the following steps: Step #1: calculation of the absolute FDS of the HALT repetitive shock stimuli Step #2: calculation of the absolute FDS of the life profile sequence to which is expected to be applied to the product Step #3: comparison of the 2 above FDS, in the range of frequencies concerned by the precipitated defect Step #4: application of a criteria to conclude on the relevance of the failure to be corrected.
