Structural optimization and reliability study of circular saw blade for shrub harvester

Shrub harvester can provide good conditions for cutting shrubs. In order to improve the operational efficiency and quality of work of the shrub harvester, for this reason, the structural parameters of the circular saw blade of the shrub harvester are changed, the structure of the circular saw blade of the shrub harvester is optimized, and the optimal parameter of the circular saw blade is obtained, and the vibration reliability of the circular saw blade of the shrub harvester is calculated, and the reliability of the circular saw blade of the shrub harvester is obtained. The results show that when the parameters of the circular saw blade of the shrub harvester are 2mm thickness, 18° front angle, and 50° chisel angle, the minimum sawing force of cutting is 47N, and the reliability of the optimized circular saw blade is obtained to be 84.2% at the threshold value of 25.
