Engineering Physics Annotation << Back THERMAL CALCULATION OF PRESS EQUIPMENT FOR SHS-COMPACTION AND THE CHOICE OF OPTIMUM TECHNOLOGICAL MODES L.S. STELMAKH, A.M. STOLIN, B.B. POLJAKOV, D.S. DVORETSKIJ The problem of optimum designing of a compression mould for SHS-compaction is discussed. The expediency of use of not isothermal method for the thermal calculation considering short duration and non-uniformity of thermal loading on its walls is theoretically proved. On the basis of mathematical modelling of the temperature fields arising in a compression mould at SHS-compaction, the variant of the optimisation problem decision for the thermal processes occurring in a compression mould is presented. This decision is used at calculation of the minimum wall thickness of the compression mould satisfying to all technological restrictions. It is shown that calculation by not isothermal technique allows to reduce essentially a thickness of a wall and accordingly weight of a compression mould.
