N2 - We have translated the results of bar modeling in N-body simulations into the language of action variables JR, Lz and Jz. We used the AGAMA package and the formalism associated with the Steckel potential. Action variables were calculated in the changing non axisymmetric potential of the model at different moments of the bar evolution. We found that at the later stages of the bar evolution, the maximum values of JR are reached at its ends, after which, upon going to the disk, JR decreases monotonically. As for Jz, the maximum values of Jz actually outline the B/PS bulge, the thickest part of the bar. Such a behavior of the action variables can be used for tests to identify the features of the bar of our Galaxy based on GAIA data.
