The method comprises the steps of constructing a multidisciplinary reliability design optimization model, introducing collaborative optimization, carrying out uncertainty analysis on the wind power gear box and introducing sequence optimization to carry out reliability analysis, constructing a multidisciplinary design optimization model based on sequence collaborative optimization, and applying a project of the multidisciplinary design optimization model to the wind power gear box; and constructing a wind power gear box multidisciplinary reliability design optimization model based on sequence collaborative optimization, and realizing multidisciplinary reliability design optimization on the wind power gear box. According to the method, a multidisciplinary design optimization theory, a collaborative optimization theory and a sequence optimization theory are combined, so that the problems that when collaborative optimization is used, consideration of uncertain factors enables compatibility constraints to become complex, system-level optimization nonlinear features are increased, and consequently design results are inaccurate are solved, and the method has the advantages of being high in practicability and the like. Therefore, the requirement of high reliability of a wind power gear box 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 multidisciplinary reliability design optimization method for a wind power gearbox based on sequence collaborative optimization. Background technique [0002] Multidisciplinary Design Optimization (MDO) is an emerging technology that emerged in the 1980s and was first applied in the field of aerospace technology. This method can fully consider the interaction and coupling between various disciplines to obtain the overall optimal design of complex systems. At the same time, multidisciplinary design optimization can shorten the design cycle and reduce development costs. [0003] In general, multidisciplinary design optimization can be divided into two categories: single-level and multi-level. In the former type of MDO, the optimizer is only performed at the system level. Each discipline can focus on the analysis o...
