For products comprised of multiple parts such as machine tools, commercial aircraft, new transportation systems and wind turbines, Mitsubishi Heavy Industries, Ltd. (MHI) is striving to improve performance and robustness through the prediction of performance by applying Multibody Dynamics (MBD) analysis to evaluate the vibration characteristics of structural components and the load transfers in machine components. We have developed a high-precision simulation model by combining MBD model and control system model for vertical precision milling machine, the performance of which is affected directly by mechanical vibration. In addition, a vibration suppression method utilizing the MBD model has been developed. This report introduces a summary thereof.
