| Abstract: | The contact problem of integrated part of machine tool is being handled with the adoption of matrix unit selfdefined by users.The finete element model of machine tool as a whole is established on the platform of commercialized softwares and the analysis on its dynamic characteristics is being carried out.Function prediction of the structure is conducted by applying this method.This method has already been applied in factories in the design of improving the structures of machine tools. |
