Research on dynamic behaviors of machine structure by dynamic BEM

Machine structure with joints was studied systematically, and a mixed modeling method based on dynamic and static fundamental solutions was introduced to establish the dynamic model of the whole structure, and the corresponding dynamic characteristics were analyzed. The machine structure can be modeled by a dynamic boundary element (DBEM). Numerical simulation analysis and dynamic experiments show that the established method improves modeling precision and efficiency, saves computing efforts but also raises analyzing accuracy of the whole structure.
