• The steady sliding state of periodic structures such as charge density waves and flux line lattices is numerically studied based on the three dimensional driven random-field XY model. We focus on the dynamical phase transition between plastic flow and moving solid phases controlled by the magnitude of the driving force. By analyzing the connectivity of comoving clusters, we find that they percolate the system under driving forces larger than a certain critical force within a finite observation time. The critical force, however, logarithmically diverges with the observation time, i.e., the moving solid phase exists only within a certain finite time, which exponentially grows with driving force.
