Investigating the Performance of Embossing on Fins Wheel of Agricultural Tractor

Abstract

The Fins wheel of the tractor was the most important part of a tractor to plough the field. Fins wheel was damaged due to lack of ability fins tractor wheels withstand bending loads as well as influenced by the age of the fin itself. This study was conducted to determine how the effects of embossing on the maximum bending load, deflection, ultimate tensile strength, and hardness which occur by using variations of the embossing number 1 and 2, and high embossing of 4, 5, 6 mm. The type of material used is JIS 3101 SS 400 with a thickness plate of 3.8 mm. This research was conducted by starting the design and press tool manufacture (punch & dies), manufacturing materials to be formed into fins wheel tractor, forming plates become fins wheel tractor, perform bending test to determine the maximum bending load strength and deflection that occurs. The experimental results showed that the finned wheel of the tractor which has two embossing with embossing height 6 mm would generate the smallest deflection of 4.93 mm and the maximum bending load of 4.0 kN. Fin wheel tractor with embossing can hold maximum bending loads greater than the soil pressure of 1.6 kN. Increasing the height of embossing will increase the hardness and ultimate tensile strength. The higher value of hardness and ultimate tensile strength was obtained at embossing height of 6 mm for 167,66 HB and 586,81 N/mm2 respectively.
