Design and finite element analysis of rotary tillage blade based on SolidWorks

The basic working principle of rotary cutter is analyzed. The 3D (3-dimensional) modeling of the rotary tillage blade is designed by using the SolidWorks software. Finite-element analysis is carried out by making use of the COSMOS sub-function, which obtains the data of working stress, deformation and stress displacement. The analysis of results shows that the parts near the assembling hole have the largest stress, and the area around blade tip has the largest deformation. This result of the study provides a valuable reference for the subsequent structure designing.
