Abstract

Abstract: The traditional prediction method of mechanical equipment failure rate is of lower accuracy, it is unable to adapt the demand of modern equipment maintenance. This paper proposes a novel PHM algorithm based on ACO and LSSVM algorithms. Using time series analysis prediction method to calculate seasonal factor and combining with ACOLSSVM algorithm to model the failure rate of an aviation device, a good experimental result is obtained, and the comparative analysis of predicted result and actual result is given.
