High accuracy estimation technique of structural vibration by virtual sensing

Virtual sensing is a method to estimate unobservable or unmeasurable state variables by combining exsisting measurement data with model information. When FE applied the virtual sensing, vibration response estimated at all nodes. it enables nodes, for example, will be possible simulate sound radiation from mechanical structure data. In this paper, illustrated how high accuracy It then examines effect of excitation force on estimation results. Based results verification, improve proposed. also tests relationship and difference between real location force. Finally, quality radiation.
