The efficiency of machining and the quality of the surface are both directly affected by the static and dynamic rigidity of the machine tool. For machine tool design and development, static and dynamic analytical evaluations are critical to achieving optimal machine tool performance under difficult and demanding machining conditions. Structural analysis is the most direct and effective control structure. Dynamic analysis and static analysis of the large machine tool is performed based on a reduced static analysis model using the ANSYS software to determine the static deformation and static stiffness of the tool. finite element method analyzes the structure, static force, modal, natural frequencies spectrum, and corresponding vibration modes of and transient state of the machine tool by considering the time-varying structural load and static and dynamic machine movements We identify the first three different frequencies-17.0, 24.5, and 37.5-by applying model analysis, which may be indicating a weak link. By comparing the data with the FEA findings, it is possible to validate the correctness and efficiency of the finite element model created for the research as well as the data quality of static and dynamic features. The difference in error between experimental static rigidity the two was 6.2%.
