This text use 3-d linear interpolation to transfer the pressure data of the impeller which get from FLUENT,The node data which we got can be provided as the ANSYS analysis to use.With the help of ANSYS,we can make strength analysis of loading pressure distribution impeller.The result enunciation the applied of 3-d linear interpolation in pump by turn the Fluid-Solid Interaction analyze match the emulation,being promise the premise of the calculation accuracy descended to reduce calculation quantity,making Fluid-Solid Interaction analyze match imitate to the fact and providing a more accurate method for impeller 's Fluid-Solid Interaction analyze.

For the high complicated surface of 3-D integral impeller,the UG NX which has strong surface modeling function is used,in the modeling module,resorting to the comprehensive utilize of curves and surfaces in the form of BSC and BBC to get the model of 3-D integral impeller.Comparing with the classic method of impeller designing,this method make sure that we can get a high precision model and also avoid the error of impeller in manufacture or surplus in casting,all the procession of this shortened the design period of products seriously and reduced production costs of centrifugal compressor.
