Design and Weldment Static Simulation Analysis of a Peanut Threshing Machine Frame Using Solidworks

Abstract

Peanut threshing is an important post-harvest process that affects work efficiency, processing time, and product quality, particularly for small-scale agricultural production. Manual threshing requires considerable labor and time, making the development of a mechanical peanut threshing machine necessary to support post-harvest mechanization. This study aims to design and analyze the frame of a peanut threshing machine using weldment static simulation in Solidworks. The frame was designed using a hollow square profile measuring 35 mm × 35 mm with a thickness of 2 mm. The analysis was conducted using a static simulation approach based on Finite Element Analysis to evaluate displacement, von Mises stress, and safety factor under a total component load of 210 N. In addition, the required number of E6013 electrodes for the Shielded Metal Arc Welding process was calculated. The simulation results showed that the maximum displacement was 0.0309 mm, while the maximum von Mises stress was 0.145 MPa. The safety factor result indicated that the frame design was structurally safe under the applied static load. The electrode requirement calculation showed that 17 E6013 electrode rods were needed for the welding process. These results indicate that the designed frame is feasible for fabrication and can support the main components of the peanut threshing machine with low deformation and stress. This study contributes to the development of a safer and more efficient peanut threshing machine frame for small-scale post-harvest mechanization.
