Two approaches are possible for kinematically driven multibody systems: a classical and a computational approach. In the classical approach it is assumed that the system degrees of freedom can easily be identified and all the kinematic variables can be expressed in terms of the degrees of freedom. When more complex systems are considered, the use of another computer-based method, such as the computational approach, becomes necessary. A V engine slider crank mechanism is an example of the complex system. In the computational approach, the kinematic constraint equations that describe mechanical joints and specified motion trajectories are formulated, leading to a relatively large system of nonlinear algebraic equations that can be solved using computer and numerical methods. In this paper, we use the computational approach for kinematic analysis of the position, velocity and acceleration of a slider crank and a V engine slider crank mechanism. The influence of nonuniformity rotation of the crankshaft on the movement of the piston will be given.
