Abstract

Coconuts are harvested by climbing the tree and cutting the nuts by hand. Manually climbing up and down the tree is hazardous and tedious. A few models of mechanical coconut tree climbers are available to overcome these drawbacks. Testing the mechanical strength and stability of the coconut tree climbers is necessary to ensure their safe performance under working conditions. The static analysis of the top and bottom frames of the farmer’s model of a sit and stand type climber was carried out separately using the ANSYS 15.0 software. Analysis was carried out for various loads of 400, 500, 600, 700, 800, 900, and 1000 N, respectively. The static analysis was interpreted with the equivalent (Von Mises) stress, equivalent elastic strain, and total deformation. The results showed that the Von Mises stress increased as the load increased. A maximum Von Mises stress of 1.5608 × 108 Pa and 6.2431 × 107 Pa, respectively were observed at loads of 1000 N and 400 N for the top frame. A maximum equivalent elastic strain of 7.845 × 10-4 and 3.138 × 10-4, respectively were observed at loads of 1000 N and 400 N for the top frame. The minimum factor of safety of 1.6 and 4.0 respectively at loads of 1000 N and 400 N for the top frame and 1.3 and 3.2, respectively at loads of 1000 N and 400 N for the bottom frame was observed.
