The invention discloses a water turbine rotor multidisciplinary reliability design optimization method considering uncertainty. The method comprises a multi-level and multi-disciplinary modeling and design optimization method for the complex mechanical system, and a multi-source heterogeneous uncertainty analysis and reliability multi-disciplinary design optimization method for the complex mechanical system based on an approximate reliability analysis method. According to a multidisciplinary design optimization method for multisource heterogeneous uncertainty analysis and reliability of a complex mechanical system based on a numerical simulation reliability analysis method, a UBMDO method is introduced into the field of water turbine rotor design, and multidisciplinary design optimization considering uncertainty is carried out on a water turbine rotor. The system hierarchical control strategy, the collaborative optimization method, the saddle point approximation method, the subset simulation uncertainty analysis method and the like are combined, the problem that the design result is inaccurate due to the fact that uncertainty factors are manually ignored in a traditional design method is solved, and therefore the requirement for high reliability of a water turbine rotor product is met.
Description
technical field [0001] The invention belongs to the technical field of multidisciplinary design optimization of mechanical products, and in particular relates to a method for multidisciplinary reliability design optimization of hydraulic turbine rotors considering uncertainty. Background technique [0002] Multidisciplinary Design Optimization (MDO) is a new technology that emerged in the 1980s and was first applied in the field of aerospace technology. Multidisciplinary design optimization is a methodology dedicated to dealing with complex, coupled engineering system design problems. Multidisciplinary design optimization is to coordinate each sub-discipline from the whole, regard the engineering design problem as a system, and then divide the engineering problem into several subsystems according to the discipline, and use the distributed computer network for unified management. Designers of each specialty, after considering the influence and requirements of other disciplin...
