MOREJON-VIZCAINO, Genovevo. Modeling and computer experiments of the compression stage in free piston engines. Ingeniería Mecánica [online]. 2012, vol.15, n.3, pp.191-200. ISSN 1815-5944.

The goal of the investigation is the development of a free piston engine with an auxiliary hydraulic bomb that substitutes the function of the hydraulic accumulator with the objective of to improve the density of power and to diminish the demands in the dynamic behavior of the components. The used method is the "Development of new products mecatrónicos". In the investigation to arrive to the new knowledge an analytic prototype is developed to carry out PC-experiments. The mathematical model is deduced for the stage of the compression, the algorithm and the analytic prototype was obtained. The results of the experiments show different restrictions in the geometry and the materials to use as well as the tendencies in the behavior of the different hydraulic parameters.

Keywords : free pistons engine; computational experiments; analytic prototypes; mathematical models; oilhydraulic.
