A Finite Element Model for 3D Elastoplastic Frictional Contact Analysis and Its Application in Numerical Simulation of Turbocharger Compressor

Abstract The finite element parametric quadratic programming (PQP) method developed based on the parametric variational principle (PVP) is used for the analysis of stress distribution of 3D elastoplastic contact problems. Particular concentration is on the numerical analysis of the impeller-shaft sleeve-shaft in a locomotive-type turbocompressor with 24 blades under combined centrifugal and interference-fit loading. The multi-level, multi-branch substructure technique of FE used takes precise simulation of complicated geometrical shapes of impeller and considerably enhances accuracy in numerical computation. The influence of fit tolerance, the wall thickness of shaft sleeve, rotational speed (centrifugal force) on contact stress distribution in the structure is discussed in detail. The results obtained provides an effective approach to achieve more reliable interference-fitting connections and more precise assembly with lower manufacturing cost in the structural design of turbocharger compressor.
