Vibrational Analysis of the Motion Process of Compressor Ring-Valve Plates

Differing from the traditional method of treating the motion of ring valve-plates as translational or inclined motions of rigid bodies, this paper originated from the concept on deformations involved in the motion processes. Emphasis of research is centered on flexural warping vibrations during opening and closing. Mechanical modelling and mathematical interpretions of plate motion with variously positioned spring systems are established, enabling theoretical solutions of model shape functions, stresses and strains. Numerical Computer results of dynamic analyses can be used as basis for improvement of compressor design with re§rod to reliability. A set of diagramatic representation of the computed circumferential distribution of the instantaneous desplacements, dynamic stresses and velocities of some ring valve-plates of an actual air compressor are hereby presented.
