Description

technical field [0001] The invention relates to the field of wind turbine gearbox design, in particular to an intelligent optimization design method and device for a planetary gear train of a wind turbine gearbox. Background technique [0002] Compared with the gearboxes of other mechanical systems, the gearboxes of low wind speed wind turbines have the requirements of complex system, more components, lightweight design and high power density. In recent years, with the increase of the single unit capacity of the unit, the coordination between the reliability and lightweight of the gearbox has become more and more difficult. [0003] Double-fed unit gearboxes generally have three-stage transmission, including two-stage planetary gear trains, and semi-direct drive gearboxes generally have two-stage planetary gear trains. Therefore, for the design of wind power gearboxes, it is particularly important to optimize the design of these two-stage planetary gear trains. important. ...

Problems solved by technology

[0004] In traditional design, a prototype is generally manufactured according to the design plan, and then the feedback design is corrected after the bench test. Time-consuming, consumable, and labor-intensive lead to a long cycle, and the test is inevitably individual, so the optimization of the plan is slow.

[0005] It can be seen that the above-mentioned existing wind turbine gearbox planetary gear train design method obviously still has inconvenience and defects, and needs to be further improved urgently.
