【摘要】：随着石油、煤炭等常规能源的日益枯竭,风能资源以其独特的优势越来越受到广大人们的关注,风电产业在未来能源战略中将占据至关重要的地位。风电增速箱是风电系统的关键部件,其设计制造技术在很大程度上制约着发电能力。本文在研究超环面行星蜗杆传动理论的基础上,将超环面行星蜗杆传动理论引入风力发电领域,设计一种新型的兆瓦级风力发电增速器——兆瓦级风力发电滚锥齿超环面行星蜗杆增速器,以促进大功率风力发电机组的快速发展的目的。主要研究的内容如下: 开展了超环面行星蜗杆传动的空间啮合理论的研究,针对兆瓦级大功率动力传动要求,设计了兆瓦级风力发电滚锥齿超环面行星蜗杆增速器的结构方案,主要包括传动的核心部分、支撑部分、润滑系统和冷却装置的设计。综合运用改进的遗传算法IP_μGA (a modified micro genetic algorithm with the strategy of Intergeneration Projection)和外惩罚函数法开展了兆瓦级风力发电滚锥齿超环面行星蜗杆增速器的主要性能参数优化设计。综合运用响应面法、有限元分析技术及正交试验设计方法,开展了增速器的结构参数的优化设计。运用正交试验设计方法来安排有限元分析方案,提取相应的计算结果,将得到的数据使用响应面法来建立一个设计变量与目标函数之间的对应关系。将该对应关系可视化显示为曲线图,通过人工调整曲线图中设计变量的取值范围来求得增速器结构参数的最优解。最后,基于UG二次开发技术构建了滚锥齿超环面行星蜗杆增速器的设计平台的基本框架,向用户提供了与UG系统风格相似的可视化设计环境。将前述性能参数优化设计嵌入到框架中,实现了预期的功能。通过参数化建模,以UG作为二次开发平台,对增速器零部件进行二次开发,减少花费在重复性工作上的时间,从而大大地提高了设计效率。
[Abstract]:With the increasing depletion of conventional energy such as petroleum coal and so on wind energy resources have attracted more and more attention due to their unique advantages. Wind power industry will play an important role in the future energy strategy. Wind power booster is the key component of wind power system, and its design and manufacture technology restricts the power generation ability to a great extent. On the basis of studying the theory of supertoroidal planetary worm drive, this paper introduces the theory of hypertoroidal planetary worm drive into the field of wind power generation. In order to promote the rapid development of high power wind turbine, a new type of megawatt wind turbine is designed, which is called megawatt wind turbine supertoroidal planetary worm governor. The main research contents are as follows: the space meshing theory of supertoroidal planetary worm drive is studied, aiming at the requirements of megawatt power transmission, The structure scheme of megawatt wind power generation supertoroidal planetary worm governor is designed, which mainly includes the core part of transmission, the support part, the lubrication system and the design of cooling device. Based on the improved genetic algorithm (IP_ 渭 GA (a modified micro genetic algorithm with the strategy of Intergeneration Projection) and the external penalty function method, the optimization design of the main performance parameters of the supertoroidal planetary worm governor with bevel teeth in MW level wind power generation has been carried out by using the improved genetic algorithm, 渭 GA (a modified micro genetic algorithm with the strategy of Intergeneration Projection) and external penalty function method. Using the response surface method, finite element analysis technique and orthogonal test design method, the optimization design of structural parameters of the governor is carried out. The orthogonal experiment design method is used to arrange the finite element analysis scheme, and the corresponding calculation results are extracted. The response surface method is used to establish a corresponding relationship between the design variable and the objective function. The corresponding relation is visualized as a graph and the optimal solution of the structural parameters of the governor is obtained by manually adjusting the range of the design variables in the graph. Finally, based on the secondary development technology of UG, the basic framework of the design platform of the spiral gear booster with bevel tooth hypertorus is constructed, which provides users with a visual design environment similar to the style of the UG system. The above performance parameter optimization design is embedded in the framework to achieve the desired function. By using parameterized modeling and taking UG as the secondary development platform, the time spent on repetitive work is reduced, and the design efficiency is greatly improved.
