Résumé

In order to investigate the effects of elastic deformation of the vane-slot on the lubrication characteristics of the vane sliding surface in a rotary compressor, a mixed lubrication analysis considering the elastic deformation has been performed for the vane sliding surface. In this analysis, the modified Reynolds equation and the elastic contact equation, within which the influence of surface roughness is considered, are solved as a coupled problem. The elastic deformation of the vane-slot is calculated by using an FEM model with two dimensional iso-parametric elements. By comparing the analysis results with that of a rigid-body model, the effects of the elastic deformation of the vane-slot on the lubrication characteristics were made clear. As a result, it is found that the elastic deformation should be considered in the analysis model of mixed lubrication between the vane and the vane-slot.
