Abstract:Based on the rigidbody and parameterized models for double electrodynamic shaker, using a control algorithm the MIMO random vibration simulation with beam finite element model is studied. By using the software Virtual.lab, a coupled rigidflexible model is created with the method of coupling the multibody dynamics rigid model and the beam finite element model. Then the coupled electromechanical lumped parameter shaker model is established in the MATLAB/Simulink. A vibration controller model is then implemented, based on existing algorithms. At this stage, the MIMO random vibration simulation test is run. Results show that the electromechanical coupling simulation method can properly carry out the closedloop control virtual random vibration test.
