Evaluating the Effect of Modelling Errors in Load Identification Using Classical Identification Methods

Figure 14

Load estimate using Method 2 with displacement sensors at DOF 1 and DOF 5. The figure shows the time-domain load estimate based on the number of modes included in the FRF matrix. Each time series shown has a 10 sec duration. Solid lines show the force (N), and the dashed lines show the moment (Nm).
