ROY CRAIG, ENGINEERING EDUCATOR AND PIONEER CONTRIBUTOR TO COMPONENT MODE SYNTHESIS

摘要

The contribution to Structural Dynamics of Professor Roy R. Craig, Jr. is recognized during a special honorary session of the 22nd IMAC. Professor Craig has pioneered the development of the component mode synthesis technology. These techniques are used to condense the information represented by dynamic finite element matrices on a subset of master degrees of freedom. The condensed representation can be analyzed at a fraction of the cost it would take to solve the full system of equations. Although originally developed for performing load analyses with linear models, the idea of component mode synthesis has lead to new developments and applications, for example, in domain decomposition and parallel processing, experimental modal analysis, re-analysis, and design optimization. In this paper, the concept of component mode synthesis is briefly reviewed, and recent developments are discussed.
