Design and Analysis of Grain Combine Based on ANSYS

This paper takes the grain combine as the research object,through the analysis and introduction of the straw returning process in the use of the combine,it is concluded that the service life of the cutter roll of the combine is the key factor affecting the use performance of the combine.Based on the stress analysis of the cutter roll structure of the harvester and the working condition of the cutter roll,the fatigue life of the cutter roll is calculated by ANSYS technology.Through the calculation and analysis,it can be concluded that with the increase of the speed of the cutter roll,the damage coefficient of the cutter roll increases continuously,resulting in the decrease of the remaining safety coefficient,affecting the human-machine safety in the use process.When the speed of the cutter roll exceeds 3500rpm,the safety performance decreases sharply.
