Study on System Compatibility Deformation Model of Rotary Tiller Under Lateral Loads

The model of rotary tillers under side loads established here is statically in determinate system. By means of FEM method, the deformation of side gearbox and right side board are calculated. Therefore the side deformations of rotary tillers under different lateral loads are discussed systematically. The results show that the rotary tiller system would bear the loads and deform unequally. Author's calculation also indicates that the lateral deforming values of right side board and side gearbox are almost the same, and more than 98% of the loads is born by the side.
