数字工程与数字孪生在航空疲劳与结构完整性领域的研究进展与展望
Research progress and prospects of digital engineering and digital twin in field of aeronautical fatigue and structural integrity
摘要
Abstract
Aeronautical fatigue and structural integrity are critical throughout the entire life cycle of an aircraft,ensuring flight safety.Digital engineering,as an integrated digital method,offers more efficient,reliable,and economical solu-tions for aircraft structural design,verification,operation and maintenance.It represents a significant future direction for aircraft structural safety design and sustainability.Central to digital engineering is the emphasis on models,with digital twin playing a pivotal role in integrating various models and measured data to achieve accurate assessments and maintenance of fatigue and structural integrity.This paper,informed by recent research findings presented at the 31st Symposium of International Committee on Aeronautical Fatigue(ICAF),reviews the progress in key technologies related to digital engineering and digital twins,alongside their applications in aircraft structural design,verification,op-eration and maintenance.The paper also offers perspectives on future developments in these technologies to encour-age further advancement and application of digital engineering and digital twin concepts.关键词
