Abstract :

      Due to expanding use of different engines in various applied items, for improving and development of engine parts, knowing the working conditions and activating forces in those are considered early design parameters. Crank mechanism is main components of the engine, which converts the reciprocating displacement of the piston to a rotary motion in Crankshaft with a four link mechanism. In order to investigation of dynamic situation of engine and determination of forces imposed on different parts of the mechanism, the need is a program through which can be calculated dynamic parameters of mechanism, for example velocity and acceleration against different angles of crankshaft. Therefore, this research kinetic and Kinematics of slider crank mechanism analysis was performed, and then this code was developed by Matlab. In order to evaluation results of Matlab cod, engine simulated in AVL EXCITE software. The results show that compare between results of Matlab and AVL EXCITE is a good conformance.
