全尺寸飞机结构疲劳试验数字孪生技术思考与探索
Thinking and Exploration of Digital Twin Technology in Full-scale Fatigue Test of Aircraft Structure
摘要
Abstract
Full-scale structural fatigue test is an important means for the development and verification of aircraft models,but its long cycle restricts the verification feedback and service use of models.The introduction of digital twin technology is expected to change the test mode and help improve the quality and efficiency of the test.Based on the characteristics and current situation of domestic full-scale structural fatigue test,the connotation and overall framework of fatigue test digital twin are proposed,and the application scenarios of digital twin in the whole cycle of the test are introduced.Key technologies such as full-life-cycle data acquisition and management,multiple structural analysis,timely and accurate test measurement and monitoring,quantitative updating of multiple uncertainties,immersion visualization and interaction are identified and analyzed.Some preliminary exploration work is also introduced in combination with an example of fuselage fatigue test.The research points out the direction for the development of digital twin technology in fatigue test.关键词
