Résumé

This paper describes methods for solving equations of the mathematical model of slider-link driven compressor, presented in the first part of the paper (see this Bulletin, reference 2007-1059). The model is used to calculate dynamic behaviour of movable machine elements, constraint forces, friction forces and unbalanced inertia forces. Simulation results compared to experimental measurements of rotation speed, good agreement between numerical and experimental data has been obtained. The model is used for analysing the influence of various parameters, such as piston eccentricity, piston stroke to diameter ratio, displacement on compressors performance. Even though the model gives detailed description of dynamic behaviour and mechanical losses, the more detailed thermodynamic characterization of the compressor should be developed for overall compressor optimization.
