Abstract In today's society, the rapid growth of energy consumption makes the social demand for energy has become more and more big, in the past, power generation, such as thermal power generation will cause pollution and great damage to the environment。 Wind energy, as a renewable and pollution-free energy, has gradually come into people's lives。 Although China's wind energy resources are very rich, but in the use of wind energy related technologies have yet to be improved, the use of wind energy equipment also need to be further improved。 As an important equipment that can affect the performance and life of the wind generator, the elastic support of the gear box is very important for the further improvement of the structure and performance of the gear box。
This subject to wind turbine gearbox elastic support as the object of study, analysis of MW class wind turbine gear box motion of elastic support, the gear elastic support structure design, 3D modeling and finite element software through analysis and calculation to ensure that elastic support to adapt to the requirements of wind turbine gearbox vibration。 The main research contents according to the requirement of the working principle of gear box elastic support, installation process and technology, elastic supporting structure for design of wind turbine gearboxes, the use of SolidWorks software platform for parts of three-dimensional modeling and virtual assembly。 By using ANSYS finite element analysis software, the static analysis is carried out, and the structure is modified and improved。 Finally, the elastic support of the gear box is parameterized, and the relevant software is designed, and the ideal product can be obtained through the input parameters。
Key words: the wind generator；gear box； elastic support；three-dimensional modeling；ANSYS finite element analysis；
