Industrial Process Measurement and Control Equipment Reliability Analysis Based on Physics of Failure

Abstract:

Industrial process measurement and control equipment is the basis for survival and development of the mechanical industry, related to the lifeblood of the national economy, at the same time, industrial measurement and control equipment widely used at high temperature and strong corrosive environment, with high reliability requirements. Traditional reliability analysis method is derived from electrical and electronic industry, based on the probability and statistics, in conformity with industrial measurement and control device characteristics, greatly limits the development of industrial measurement and control industry reliability, this paper presents a reliability based on failure physics theory analysis method, found the fault mode, with the simulation analysis and physical test, the product has carried on the accurate life is expected to verify the feasibility of this method, the reliability method worth to further research and promotion.
