概要

Mode contribution is often utilized to analyze system dynamics. However, it may be dispersed over a large number of modes and difficult to understand for system dynamic characteristic with high mode density. New method is developed to solve this problem including such system where recurring deformation modes (principal modes) are extracted by performing singular value decomposition on deformation patterns of the response. By using this method, the systems can be modeled with substantially smaller number of degrees of freedom compared to the modal solution. The method offers on more efficient approach for analysis of systems with dense modes.
