【摘要】：中国风能资源丰富,开发潜力巨大,必将成为未来能源结构中一个重要的组成部分。我国大型风力发电机制造业基本从零起步,目前已经掌握了750KW至6MW的风电齿轮箱零部件的设计制造技术,并实现了批量生产。但总的来说,关键零部件设计制造技术仍是我国风机制造业长期发展的最大瓶颈。从设计到制造还依赖国外技术,没有完全摆脱引进、模仿、再引进、再模仿的模式。风电齿轮箱是一种重载、低速、增速齿轮传动装置,其工作的条件是无规律变向风力作用及强阵风冲击的变载荷,在工作过程中,系统受力情况复杂。对风电齿轮箱力和变形情况进行研究有助于改进设计,从设计的角度降低振动,保证其设计寿命和系统的可靠性,对我国风电技术发展有着重要的意义。在国外,进入风电场的风电机组必须通过认证。在认证的发展和应用领域一直处于领先地位的欧洲国家,例如德国、丹麦和荷兰,由于其技术在世界上一直处于领先的水平,其认证体系也是最完善的。本文主要是为了使齿轮箱通过德国船级社风电齿轮箱认证体系,做的一项必不可少的行星齿轮均载测试,以验证风电齿轮箱行星机构的设计是否满足设计要求。在本论文研究中,主要展开了如下工作：介绍了GL认证相关的技术要求,研究了测试加载系统的原理以及测试加载系统的建立。完成了满足GL风量齿轮箱认证要求的一级齿圈应变测试方案的制定,以及应变片的粘贴、齿轮箱箱体内部的布线。研究确定了GL要求测量的相关量计算原理及计算的方法。通过不同载荷情况下行星传动试验及试验数据的分析处理,得出实际的均载效果和工程设计用的试验数据。总之,通过研究,基本掌握了满足GL认证要求的应变测试方法,以及相应的数据分析处理方法。不仅提高了专业技术水平,而且对今后企业行星齿轮的设计和加工将有大的指导；对提升行星齿轮产品综合性能指标、齿轮箱的产品质量及以后更加深入的研究都有一定的参考价值和意义。
[Abstract]:China is rich in wind energy resources and has great potential for development, which will become an important part of the energy structure in the future. China's large-scale wind turbine manufacturing industry basically starts from scratch. At present, we have mastered the design and manufacturing technology of 750KW to 6MW wind power gearbox components, and have realized batch production. But in general, The design and manufacturing technology of key parts is still the biggest bottleneck in the long-term development of fan manufacturing industry in our country. From design to manufacture, we still rely on foreign technology, without completely getting rid of the mode of importing, imitating, reintroducing and imitating. The gearbox of wind power is a kind of gear transmission with heavy load, low speed and high speed. The working conditions of the gearbox are irregular wind force and variable load caused by strong gusts. The study of the force and deformation of the wind power gearbox will help to improve the design, reduce the vibration from the design point of view, ensure the design life and the reliability of the system. It is of great significance to the development of wind power technology in China. In foreign countries, wind turbines entering wind farms must pass the certification. European countries, such as Germany, Denmark and the Netherlands, have always been in the leading position in the field of development and application of the certification. Since its technology has always been in the leading level in the world, its certification system is also the most perfect. This paper is mainly to make the gearbox pass the German Classification Society wind power gearbox certification system, do an indispensable planetary gear load test. To verify that the design of the planetary mechanism of wind power gearbox meets the design requirements. In this thesis, the main work is as follows:. This paper introduces the technical requirements of GL authentication, studies the principle of test loading system and the establishment of test loading system. The first grade gear ring strain test scheme which meets the requirements of GL air volume gearbox certification is made, the strain gauge is pasted, and the inner wiring of the gearbox box is arranged. The calculation principle and calculation method of the relevant quantity required by GL are studied and determined. Through the analysis and processing of the planetary transmission test and test data under different loads, the actual average load effect and the test data for engineering design are obtained. In a word, through the research, we have mastered the strain testing method which meets the requirements of GL certification, and the corresponding data analysis and processing methods, which not only improve the professional technical level, Moreover, it will have great guidance for the design and processing of planetary gears in enterprises in the future, and will have certain reference value and significance for improving the comprehensive performance index of planetary gear products, the product quality of gearbox and the further research in the future.
