Damage Tolerance Approach in Designing and Maintaining Truck Trailers

该项目旨在开发一种设计和维护卡车拖车的损伤容限方法。结合现场试验和计算模拟，采用机器学习方法生成载荷谱。遵循航空航天领域成熟的损伤容限理念，对疲劳裂纹扩展和疲劳寿命进行预测。此外，还将在拖车设计中进行结构优化。该项目预计将彻底改变澳大利亚卡车拖车行业的设计和维护实践。它应该为拖车制造商和用户提供显著的好处，如延长卡车拖车的生命周期，减轻皮重和增加营业利润。

This project aims to develop a damage tolerance approach in designing and maintaining truck trailers. Combined with field test and computational simulation, machine learning will be used to generate loading spectrums. Following the damage tolerance philosophy, a mature approach in aerospace industry, the fatigue crack growth and the fatigue life will be predicted. In addition, structural optimisation will be applied in trailer design. This project expects to revolutionize the design and maintenance practices in Australian truck trailer industry. It should provide significant benefits, such as prolonging the life cycle of truck trailers, reducing the tare weight and increasing operating profit, to both trailer producers and users.
