Abstract
The Ulam model analog of the Fermi acceleration for the sine-Gordon solitons is investigated. The motion of soliton between two potential walls, one of which is periodically oscillating, is studied. With the help of the Melnikov method the expression for the threshold of stochasticity in soliton motion is found.
