The Department of Heavy NC machine tool has a great influence on the performance of machine tools. The 30%-50% static stiffness, more than 50% of the dynamic stiffness depends on the combining part, and the influence on damping reached 90%.Machine tool with the Department of static and dynamic performance directly determines the accuracy and reliability of Heavy NC machine tool. Therefore, in conjunction with the Department of research and design of Heavy NC machine tool is very important. In this paper, based on Hertz contact theory, the contact at the micro level, considering the combination form of machine tool, and the machine joints as a virtual media simulation, a combination of virtual media framework, and calculation of characteristic parameters of the virtual material, then use the ANSYS Workbench to solve the combination of the natural frequency of the whole, the first five order modal extraction. Using modal test technology, get the specimens of natural frequency and damping of the true value, natural frequency are compared with theory, prove the formula of virtual media is reliable, can be used in the modeling of heavy machine tool.
