Kinematic and Kinetic Analysis of MF285 Tractor Engine

Farm tractors play a key role in farm mechanization all over the world. They supply the required power for most of the agricultural operations such as soil cultivation, planting, weed control and harvesting. ITM 285 is the most popular tractor in IRAN. In spite of its high production and usage, less research has been conducted on its performance optimization. Performance of its engine depends on different parameters such as its components and their interactions. In this research, to demonstrate the operation of engine components and their interactions during engine operation, kinematic and kinetic analysis was conducted for key elements of the engine. The results were analysed in terms of velocity and acceleration of the piston, connecting rod and crankshaft. Also forces and moments acting on the moving crank of the crankshaft were computed. It was concluded that the results of the research are useful for stress and fatigue analysis in order to optimize the engine components and make them durable and lighter in the future.
