In design of valve train systems, it is useful to predict the dynamic behavior to calculate the loads, stresses and contact losses prevention. In this paper a kinematic model was developed over the cam discrete data, building a piecewise cam curve known as Spline, from the continuous curve is possible to predict the valve train kinematic characteristics, evaluating the values of displacement, velocity and acceleration of all valve train components. Based on the kinematic model results, the values of displacement imposed by the cam rotation are applied as input data to the dynamic model, that from a multiple mass system considering stiffness and damping of the components allows to know the valve train vibration behavior calculating the loads, stresses and losses of contact.
