Abstract

The objective of this paper is to design the threshing drum for paddy thresher and to analyze the structural behaviors on the threshing drum due to applied centrifugal force and toque on it. This paper discusses about the threshing drum of paddy thresher as axial flow type produced in Aung-Paddy Thresher Industrial Zone at Mandalay. The threshing drum consists of threshing discs, bars, teeth, hubs, disc supports and blades which are constructed with gray cast iron. The threshing drum diameter is 450 mm and length of drum is 1050 mm. The speed of threshing drum is 640 rpm at power supplied 3.649 kW. Weight of threshing drum, power and threshing torque are estimated in this paper. Solid Works software is used for modeling and analysis of the threshing drum of paddy thresher. The stress distribution on threshing drum is expressed by theoretically and numerically approaches. The threshing drum was analyzed by using three different materials. Von-Mises stress and effective strain of Low Carbon Steel is lower than the other materials. So the suitable material is Low Carbon Steel. The simulation and theoretical results data of maximum von-Mises stress are 3.930 MPa and 4.741 MPa for Low Carbon Steel. The percent error is 17%. Von-Mises stress of Low carbon steel does not exceed yield strength value of 276 MPa. So the design is satisfied.
