ShareTHE COMPRESSOR NOISE -SHELL AND STEEL MATERIALS.
Author(s) : KAWAI H.
Summary
THE NOISE OF A SMALL HERMETIC COMPRESSOR IS MOSTLY RADIATED BY VIBRATION OF SHELL. THEREFORE, AN EFFECTIVE APPROACH IS TO PROVIDE A SHELL STRUCTURALLY LESS RESPONSIVE TO THE VIBRATION SOURCE. BY APPLYING FINITE ELEMENT METHOD AND MODAL ANALYSIS TECHNIQUES TO THE STEEL COMPRESSOR SHELL, THE AUTHORS OBSERVED THAT: 1) THE NODE OF A PRINCIPAL MODE ON A SPHERICAL SURFACE SHALL BE FIXED REGARDLESS OF CURVATURE AND IS LOCATED ON THE SAME CENTER ANGLE ; AND 2) STRAIN HARDENING EXPONENTIAL AND LANKFORD VALUE OF STEEL AFFECTED THE SOUND RADIATED FROM THE COMPRESSOR SHELL. THE NOISE IS REDUCED ABOUT 3 DECIBELS (A) BY USING THESE CHARACTERISTICS.
