Investigation of Performance of Twin Screw Compressor Using FEA

Abstract

A twin screw compressor with 5 teeth is designed, modeled and analyzed deformations, stresses, frequencies, directional deformations and shear stresses. The modeling and assembly is done in Creo 2.0. Static Structural analysis, Modal analysis are done on the twin screw compressor by varying rotational speeds 2000rpm, 4000rpm, 5000rpm to determine deformations, stresses and frequencies. Random Vibration analysis is done at speed 5000rpm to determine directional deformations and shear stresses. The analysis is done using materials Steel, Titanium alloy and Nickel Alloy. Analysis is performed in Ansys 14.5.
