Mathematical model of slider-link driven compressor. I.

Author(s) : DAGILIS V., VAITKUS L., KIREJCHICK D.

Summary

In the model dynamic behaviour of the piston, the slider and the crankshaft are analyzed theoretically. Constraint forces, friction forces, unbalanced inertia forces and sliding speed at each pair of movable machine elements are obtained. Attention is focused on the friction forces; an advanced model of slider bearings with variable eccentricity ratio (and variable friction coefficient) is used. Some of the concepts introduced in the paper can be applied also to connecting rod driven compressors. The detailed simulation model developed by the authors is targeted for evaluation and minimization of losses due to friction and compressor vibrations. The model could be a useful tool for comparison purposes, to characterize compressors and to assist designers at the early stage of compressor design. See also this Bulletin, reference 2007-1060.
