750kW风力机组齿轮箱动力学仿真分析
The dynamic simulation analysis of 750 kW wind turbine gearbox
摘要
Abstract
The fierce vibration produced by the operation of wind turbine generator system has a tremendous influence on the gearbox movement precision and gear life. In view of this situation, experiments were carried out to redesign and modeling of gearbox in this study. Based on multi-body system dynamic method, modality vibration, impact - contact theory, take 750 Kw wind turbine gearbox as the research object, through gearbox simulation analysis, gear meshing and the impact force as well as the variation curve of the kinetic energy along with the time were obtained. In addition, high speed gear shaft was also analyzed by modal, and the curved vibration mode was obtained by the high speed gear shaft modal analysis, and high speed gear shaft, planetary gear, planetary frame, gear zl were turn to the flexible body for stress analysis, gear stress distribution graph was obtained, which provided a foundation for the gearbox overall dynamics characteristic analysis and optimization design.关键词
