Abstract

The invention discloses a converter multidisciplinary optimization design method based on multi-physics field coupling. The converter multidisciplinary optimization design method comprises the following steps: S1.1, selecting a target which needs to be optimized in a converter model, carrying out the parametric modeling of the target, and obtaining a three-dimensional parametric model; S1.2, extracting geometric information of a preset area in the three-dimensional parametric model, modifying configuration parameters to enable non-geometric information to be output, and outputting an intermediate file; S1.3, establishing an optimization process according to the intermediate file, establishing a CFD thermal simulation model, extracting parameterized size variables needing to be optimized, and determining an optimization target and constraint conditions; and S1.4, executing optimization to obtain optimized geometric parameters. The converter multidisciplinary optimization design method has the advantages that the multidisciplinary separation problem existing in traditional design is solved; the design requirements of different disciplines can be fully considered; and the design period of the high-power converter is greatly shortened, and the design cost is reduced.

Description

technical field [0001] The invention relates to the technical field of converter design, in particular to a multi-disciplinary optimal design method for converters based on multi-physics field coupling. Background technique [0002] With the continuous development of modern industry, the requirements for converter cabinets are getting higher and higher. New converter cabinets with small volume and high heat consumption have gradually become the mainstream of market demand, while converter cabinets with small volume and high power consumption must require There is a good heat dissipation design. Overheating of devices will inevitably reduce the reliability and safety of converter cabinet products, which will lead to high design costs. In order to ensure the reliability of the whole system of the converter cabinet, engineers need to use simulation tools to ensure a good heat dissipation design of the converter cabinet. [0003] The rapid update of converter cabinet products ...
