AI Technical Summary

Technical Problem

Existing technologies cannot quantitatively and dynamically map the relationship between material degradation and burst pressure shift in real time when predicting the life of rupture discs, resulting in limited prediction accuracy and lack of dynamic monitoring. In particular, the failure mechanism of materials is difficult to be effectively captured in complex service environments.

Method used

A method for modeling the life of rupture discs based on material degradation is established. By constructing a real-time sensing field of multi-source service environment parameters and rupture disc status, and combining a multi-physics field coupling model of chemical corrosion thinning, tissue softening and fatigue damage, the material damage variables are calculated in real time. The remaining life is then predicted using a particle filtering algorithm, thereby realizing dynamic monitoring of the rupture disc status.

Benefits of technology

It enables real-time quantitative characterization of the microstructure evolution of rupture disc materials, improves the accuracy and real-time performance of lifetime prediction, and can output the remaining lifetime probability distribution with confidence intervals, providing reliable safety warnings and enhancing the inherent safety of industry.

Abstract

This invention discloses a method and system for modeling the life of rupture discs based on material degradation, belonging to the fields of computer-aided engineering and pressure vessel safety technology. The method includes: establishing an initial constitutive model and material fingerprint database for in-service rupture discs; constructing a real-time sensing field of multi-source service environment parameters and rupture disc state parameters; establishing a material property degradation model coupled with a chemical corrosion thinning sub-model, a high-temperature tissue softening sub-model, and a fatigue damage accumulation sub-model; constructing a dynamic mapping equation between the amount of microscopic material degradation and the macroscopic burst pressure shift; using a particle filtering algorithm to achieve dynamic prediction and reliability assessment of remaining life; and employing an edge-cloud collaborative architecture. This invention solves the technical problem of limited prediction accuracy caused by the disconnect between macroscopic monitoring and microscopic mechanisms, achieving quantitative mapping and dynamic sensing of microscopic degradation and macroscopic failure.
