Abstract
A new test method is developed to evaluate the ultimate values of temperature rise of a machine-tool structure based on a short period data obtained during its warming-up run. In this method, a machine-tool structure is modelled by the finite element method and analyzed in terms of the eigenvalue problem of the thermal equation. This yields the characteristic curves of the temperature rise of the structure in the form that they contain unfixed parameters, the values of which depend on the strength of heat sources. Then by determining the parameters so that the characteristic curves fit the measured ones obtained during the warming-up run, one can identify the strength of heat sources and then the ultimate values of the temperature rise with regard to any point in the structure. Experiments are carried out to verify the effectiveness of the method.
