Considerations

Abstract

Abstract. In the present paper, it is considered vibrating system acting by a rotation cam, which has a constant angular velocity and a motion law saw-tooth type. Using the Lagrange formalism or the Newton one, the motion mathematical model of the valve is obtained. For a numerical application, the motion differential equation is integrated with the help of integral Laplace transform. Thus, results the motion law of the valve under the form of a time function. The determination is made in two evaluation system in order to obtain a bigger accuracy of the results.
