| 摘要： | Reliability Based Design Optimization (RBDO) is a process of optimizing under uncertainty to obtain a reliable (in the probabilistic sense) optimum for a design, which is robust under the expected variability inherent in realizing the design. In this case, we are optimizing the design of a ground vehicle to reduce weight while maintaining or improving durability. Like any optimization, it is best done on a system level. When optimizing under uncertainty, considering a large number of sources of variability makes the optimization method more robust. The objective is to improve the RBDO process, expanding from component optimization to system optimization of a ground vehicle, consider more sources of uncertainty and use a multi-physics and multi-scale approach. This requires greater computing power than has previously been applied to such optimizations. |
