Development of a Lumped-Parameter Model for the Dynamic Analysis of Valve Train Systems 2004-32-0051

In this work a lumped-parameter model, able to simulate the dynamic behavior of different types of valve train systems, was developed. Among the various aspects, the rocker arm flexibility, the valve lash, the possibility that the mechanical elements lose contact with each other and the possible impact of the valve in its seat were taken into account. The model includes two different descriptions of the valve spring, which can be schematized either by an ideal elastic reaction or by a multi-mass scheme, including the possibility of contact among adjacent masses.
