| Abstract: | In the framework of Newtonian mechanics and small-amplitude approximation,the motion equation of the non-relativistic particles in a periodic potential in space and time reduced to Duffing-equation with damping and forced terms,analyzed the 1/3 frequency resonance in the system using Multi-scale method;discussed stability of the system by Poincare method;found the critical condition of the system;revealed the after back bending phenomenon of resonance curve;discussed the jump phenomenon in the system.The re... |
