Analysis and Optimization of Vibration Characteristics of Corn No-till Planter
摘要
Abstract
Corn no-till seeders generate vibrations during operation,which can affect the efficiency and production quality of the seeder.Therefore,it is important to analyze and optimize its vibration characteristics.Firstly,the vibration charac-teristics of the planter,including natural frequency and vibration pattern,were determined through experimental tests and finite element simulations.Then,various optimization methods,such as structure optimization and material optimization,were used to improve the vibration performance of the planter for the problems in the vibration characteristics.Finally,the performance improvement of the optimized seeder was verified by experimental validation and simulation.The research re-sults showed that the optimized design can effectively reduce the vibration amplitude of the planter and improve the effi-ciency and production quality of the planter.关键词
