Hysteretic phenomenon is studied for an underdamped commensurate three layers model consisting of two harmonic chains that both move over the substrate. In the depinning process, two critical points F-1 and F-2 are found. In the pinning process, two critical points F-3 and F-4 are also found. The dependence of four critical forces on the system parameters is investigated. The analytical result of critical force F-1 is obtained which is in good agreement with the numerical one.
