System reliability based vehicle design for crashworthiness and effects of various uncertainty reduction measures

摘要: Reliability-based design optimization of automobile structures for crashworthiness has been studied by many researchers using either single component probabilistic constraints or failure mode based constraints, while system reliability considerations are mostly disregarded. In this paper, we perform (SRBDO) an and analyze the effect allocation in different modes. addition, effects various uncertainty reduction measures (e.g., reducing variability material properties, error finite element analysis) investigated tradeoff plots reduction, structural weight generated. These types can be used a company manager to decide whether allocate resources employing allocating excess protect against unreduced uncertainties. Furthermore, relative importance members crash scenarios is quantified.
