Slider-link driven compressor (II). Simulation results

Abstract

The model of slider-link driven compressor is
used to calculate dynamic behaviour of movable machine
elements, constraint forces, friction forces, unbalanced
inertia forces. Simulation results were compared to experimental
measurements of rotation speed, good agreement
between numerical and experimental data was 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. The attempt to performe optimization of
compressor parameters based on criterion of minimal mechanical
losses does not give satisfactory results. The
model with more detailed thermodynamic characterization
of the compressor should be developed for overall compressor
optimization.
