Damage Tolerance Approach in Designing and Maintaining Truck Trailers

本项目旨在开发一种设计和维护卡车挂车的损伤容忍度方法。结合现场测试和计算模拟，机器学习将用于生成载荷谱。按照航空航天工业中成熟的损伤容限理论，对疲劳裂纹扩展和疲劳寿命进行预测。此外，结构优化将应用于拖车设计。该项目有望彻底改变澳大利亚卡车挂车行业的设计和维护实践。对挂车生产企业和使用企业都能带来显著的效益，如延长挂车的生命周期、减轻其自重、增加营业利润等。

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.
