Analytical manner of degree of cold energy cycle structural body temperature and design device null of die device

摘要

PURPOSE:To shorten a designing process by performing an approximate integral operation by a boundary element method and based on the average value of flux density among the specific times of each thermal cycle and based on a 3-dimensional analysis model of a thermal cycle structure and then obtaining the temperature change of this structure. CONSTITUTION:The shape data that prescribe a thermal cycle structure are inputted to a computer by a data input means 1, and a modeling means 2 produces a 3-dimensional analysis model of a metallic model or a cooling device based on the shape data. At the same time, the conditional data that prescribe a thermal cycle of the metallic mold are also inputted to the computer by the means 1 and then added to the 3-dimensional analysis model to undergo an integral operation by an arithmetic means 3. That is, the temperature change of the thermal cycle structure is obtained from an approximate integral operation that is carried out by a boundary element method based on the average value of heat flux density among the specific times of each thermal cycle as well as the 3-dimensional analysis model of the thermal cycle structure. As a result, a designing process can be shortened.
