METHOD AND APPARATUS FOR IDENTIFYING THERMOPHYSICAL PROPERTY VALUES

摘要

PROBLEM TO BE SOLVED: To provide a method for identifying the thermophysical property values of a material that is difficult to be measured easily. SOLUTION: The method for identifying the thermophysical property values includes a process of measuring the temperature of a body to be measured made of a plurality of materials; a process of performing the temperature simulation of the thermophysical property value of the body to be measured as input parameters; a process of obtaining the temperature estimating expression for estimating the temperature at an arbitrary time for an arbitrary component in the body to be measured with the thermophysical property value from a temperature simulation result as an input parameter; a process for identifying, as the thermophysical property values, the value of the input parameters for giving the minimum value of a design evaluating function comprising actually measured temperature, measured at an arbitrary time for an arbitrary component and estimation temperature obtained by the temperature estimating expression.
