模拟加速腐蚀专家模拟器软件在美海军飞机腐蚀损伤评估中的应用

摘要

This paper describes the planned development of an aircraft structure corrosion damage evaluation modeling and simulation analysis system for predicting the degradation of aircraft structures due to Pitting, Stress Corrosion Cracking and Exfoliation forms of corrosion, which are the primary sources of corrosion-related failures of aircraft. The software is ob-tained by modification of the existing accelerated corrosion expert simulator ( ACES) , and is composed of an assembly of physics-based procedural algorithms, empirical-statistical models from test data and heuristic AI methods for representing knowledge from subject matter experts and lessons learned.%介绍了美国海军规划开发的飞机结构腐蚀损伤评估建模和仿真分析系统，预测了由点蚀、应力腐蚀开裂和剥蚀引起的飞机结构腐蚀损伤性能退化趋势，这三种腐蚀类型是海军飞机相关腐蚀故障的主要来源。该系统是通过扩展现有加速腐蚀专家模拟器( ACES )软件产品而获得，软件系统由基于物理数据的程序算法、基于试验数据的经验统计模型和人工智能方法组成。
