| Abstract: | Temperature distibution of a reduced mechanical model of large machine frame is obtianed from numerical method and experimental measurement. Based upon these values, the thermal deformation of the structure is caicuated using analysis program for static.A way is of fered for predication defromation and emperature compensation of large machine frame in non-homogenous field. |
