EQUIVALENT FORCE CONTROL METHOD WITH ACCELERATION CORRECTION FOR REAL-TIME SUBSTRUCTURE TESTING OF A SPLIT-MASS SYSTEM

摘要：

Real-time substructure testing (RST) is a hybrid simulation technique recently developed to evaluate structural dynamical responses,and the equivalent force control (EFC) method is an implementation scheme of RST using implicit integrations. This paper proposes an acceleration correction scheme to improve the coupling between two substructures. Stability analyses of the EFC method on a split mass system are conducted to illustrate the effectiveness of the correction. Analysis results show that the correction improve stability and accuracy of the method. In addition,the mass ratio of the physical mass to the numerical mass is no more a constraint for test design. Finally,simulations are used to support analytical results.
