Structural analysis and Design modification of The Compressor Skid of Helium Liquifier Plant

Now days, Compressors are widely used in gas gathering, gas processing, and gas storage, chemica l and refining applications. Compressors are mounted on t he its support structure(skid) to carry its weight, to mai nt in its alignment and to assist in carrying the different s tatic and dynamic loads . So, maximum stress, maximum shear s tress and deflection are important criteria for the desig n of the skids. This report is the work performed towards th e optimization of the compressor skid with constraint s of maximum shear stress, equivalent stress and deflect ion of skid under maximum load. . This paper represents a case study of the compressor skid of Helium Liquifier/Refrigeration(HRL) plant In IPR(Institute of Plasma Research) on which high speed, oil injected, rotory, single stage gas compressors are mounted. By using FEA tool approach is made for the investigations of cri ti al stresses. Structural systems like the skid can be easily analyzed using the finite element techniques. A sen sitivity analysis and taguchi method is is carried out for H igher life span and weight reduction. So a proper finite eleme nt model of the skid is to be developed. The skid is modele d in Solid works2011. FEA is done on the modeled chassis using the ANSYS11 Workbench ,and validates all result by stru ctrural software STAAD.ProVi8, which include, Indian and gl obal codes.
