| Research Abstract |
In order to achieve real-time dynamic simulation of MDOF structural systems, investigation of the method such that a logic circuit that performs the step-by-step numerical time integration of the equations of motion of the system is created, and is implemented to an FPGA-based system. Case study on several types of linear and nonlinear MDOF system models shows that use of resource sharing in logic synthesis is crucial for effective application of FPGA to real-time dynamic simulation. Implementation of required functional elements for the real-time hybrid simulation using a model with large number of DOF is also investigated to illustrate the applicability of the methodology to dynamic testing.
