DYNAMIC ANALYSIS OF A ROTOR-JOURNAL BEARING SYSTEM FOR TWIN-ROTARY COMPRESSORS.

Author(s) : HATTORI H., KAWASHIMA N.

Summary

A ROTOR-JOURNAL BEARING SYSTEM FOR A TWIN-ROTARY COMPRESSOR HA S BEEN NUMERICALLY ANALYZED TO ESTIMATE THE RELIABILITY AND TO OPTIMIZE THE BEARING DESIGN. FOR ROTARY COMPRESSORS, LARGE DYNAMIC LOADS ACT ON THE ROTOR. THEY ARE UNBALANCED FORCES DUE TO ECCENTRIC ROTATION PARTS AND GAS FORCES INDUCED BY THE DIFFERENCE IN PRESSURE BETWEEN COMPRESSION AND SUCTION GASS THE ROTOR-JOURNAL BEARING SYSTEM BECOMES NONLINEAR. SUCH A ROTOR SYSTEM IS SOLVED AS A COUPLED PROBLEM OF MOMENTUM EQUATIONS AND REYNOLDS EQUATIONS FOR ALL THE BEARINGS.
