Dynamic analysis of the connecting rod is similar to dynamics of the crank shaft since these components form a slide crank mechanism and the connecting rod motion applies dynamic load on the crank pin bearing. Reis et al. crank slider mechanism are shown in the following table. Vibrations of these mechanisms are the main source of noise and fatigue that lead to short useful life and failure. The acceleration at a point is compared with the results from the reference. 4. Slider crank inversion 1 In a slider crank mechanism depending on its application either the crank is the input link and the objective is to determine the kinematics of the connecting rod and the slider or the slider is the input link and the objective is to determine the kinematics of the connecting rod and the crank. mErkaya performed the kinematic and dynamic analysis of a modified slider crank mechanism characterized by an additional eccentric link between connecting rod and crank pin 2 . 465542 a 3 1.
