Structural Analysis of Fan Section of Air Handling Unit KMW ZR 30 11/22
on Dynamic Load Defined by Seismic Spectrum OLKILUOTO 3

3. Results

3.1. Modal analysis
As a result of modal analysis first 100 frequencies and mode shapes were calculated, see
Table 1. The examples of the mode shapes (in the form of displacements) are presented
at the Fig. 11, 12, 13, 14 and 15.
