Abstract
The piston secondary motion significantly influences the major characteristics of lubrication in a reciprocating compressor, such as the oil
leakage, the piston slap phenomenon and the frictional power loss. Therefore, the design parameters governing piston dynamics should be
carefully determined based upon a reliable dynamic characteristic investigation. As a preliminary research step, this paper is concerned with
the finite element analysis for the piston dynamic response. By coupling FDM for the lubricating pressure field with FEM for the piston
dynamic motion, we numerically approximate the lubricant–structure interaction in a reciprocating compressor. Numerical results
illustrating the theoretical work are presented.
