摘要：A new technique of dual-compatibilities free-interface component mode synthesis (CMS) was derived by transforming link substructure into super element with Guyan static condensation. The new CMS technique has high calculation accuracy, can efficiently reduce degree of freedom (DOF) of the system, thus, it has a widespread application prospect in dynamic analysis of the structures containing nonlinear link components such as Lead Rubber Bearing (LRB), nonlinear spring, etc. Based on the new CMS technique and the general free-interface CMS method, the inherent characteristics of a truss bridge, rigid or LRB linked, in the Automatic Container Terminal (ACT), was compared. The results show that LRB has obvious effect on truss bridge structural frequency modulation. Structural dynamic model similarity principle with respect to inherent characteristics is achieved with dimensional analysis method. Accordingly, a miniature model for the truss bridge is designed to test frequency response by the hammer method. The results of model test and prototype simulation prove with each other, that the simulation results and the test design are reliable, also validates the proposed CMS technique and the LRB's effect on frequency modulation
