Thermal Characteristics Analysis of Nuclear Power CNC Wheel Groove Milling Machine Based on Finite Element

Abstract:

For nuclear power CNC wheel groove milling machine in the work under the influence of a variety of heat sources, establish the finite element model of machine, using finite element analysis software ANSYS, analysis and thermal-structure coupling of heat source in the processing state mechanism, thermal key points out machine, the effect of deformation on the machine geometric accuracy evaluation of heat, and the machine thermal optimization analysis of corresponding, deformation of machine in the three direction. The results show that: the machine in machining spindle heat is an important factor affecting the machining accuracy of machine tools, and heat through various ways to machine tool bed, causing warping, guide rail bending, through this analysis provides reference for analysis and optimization design for the machine tool thermal deformation.
