| The internal flow is the combined compressor aerodynamic problems more complex.Through the numerical calculation can get some preliminary results,but to fully understand some hidden dangers in the real field,air compressor flow law and design,must be with the aid of compressor test.if you want to do this,must to design compressor test rig in advance,so,need to design and research compressor test rig.This paper from the test rig design requirement,from input to the combined compressor design layout to design of test pieces and stator rotor,introduces the structure design of a combined compressor test,design,strength calculation and vibration analysis of the main parts,ration and the test of vibration,frequent oil spills and other problems are analyzed,Through the particular analysis of critical speed characteristic to the rotor system,optimized support stiffness of the rotor,design squeeze-film damper,control assembly quality,reasonable clearance choose and other measures,effectively solve practical problems in engineering application,finally,the combination of the compressor test pieces to complete the design and processing and test verification,show that the rationality of the structure design of test pieces,a major obstacle clearing model development,ensure the development schedule of type compressor,And can provide useful reference for the design of other compressor test pieces. |
