Utilizing ABAQUS to Analyze the Active Vibration Suppression of Structural Systems
نویسندگان
چکیده
ABAQUS can be utilized in the numerical simulation of active feedback control for the purpose of vibration suppression of structural systems. Using the example of active control of a cantilever beam, the Positive Position Feedback (PPF) control algorithm is coupled into an ABAQUS dynamical structural model with the assistance of user-defined subroutines. The transient response of the beam with and without the active control is examined. For a cantilever beam configuration consisting of aluminum facings and a core composed of foam and piezoelectric shear actuators, the ABAQUS solution is found to be in good agreement with experimental values from previous work.
