Improving the fatigue life of a vehicle knuckle with a reliability-based design optimization approach

A major issue in vehicle industry is the presence of variability in the physical properties and manufacturing processes. Deterministic approaches are unable to take into account these variabilities without leading to oversized structures. The necessity of assessing the robustness of a particular design requires a new methodology based on reliability analysis and design optimization through probabilistic models of design variables.     

掺矿渣微粉混凝土抗冻性能研究

本研究以掺入矿渣粉的C40及C50混凝土为基准,对不同掺量矿渣粉的混凝土抗冻融性能进行研究,在C40混凝土中等量掺入0%,10%,20%,30%,50%矿渣粉,C50混凝土中等量掺入0%,10%,30%,50%矿渣粉,实验结果表明C40,C50混凝土均在矿渣粉掺量为30%时抗冻性能最好,且对比C40与C50混凝土,C50混凝土的抗冻融性能强于C40混凝土。
