Design of the container for hot isostatic pressing of a diesel engine piston top
Luleå University of Technology, Department of Engineering Sciences and Mathematics, Mechanics of Solid Materials.ORCID iD: 0000-0002-7514-0513

Abstract [en]

Numerical simulations of the hot isostatic pressing (HIP) process for manufacturing of a piston top have been used to achieve near net shape in this work. The shape of the container is optimised by repeated simulations of the manufacturing process. The application is a piston top for a large diesel engine. The aim is to contribute to the development of an integrated computer based tool for the design and manufacture of hot isostatically pressed products. The computer aided concurrent engineering (CACE) system which is integrated using a relational database includes the solid modeller of a computer aided design system, codes for non-linear finite element analysis (FEA), and data from a coordinate measuring system (CMM). Predictions of near net shape geometry obtained numerically are in tolerable agreement with experimental measurements. The model is based on an associated flow rule and linear isotropic hardening is assumed, the material properties correspond to AISI 304 steel.
