## Abstract

This is the second part of a two‐part series on forced lattice vibrations in which a semi‐infinite lattice of one‐dimensional particles {x_{n}}_{n≧1}, (Formula Presented.) is driven from one end by a particle x_{0}. This particle undergoes a given, periodically perturbed, uniform motion x0(t) = 2at + h(yt) where a and γ are constants and h(·) has period 2π. Results and notation from Part I are used freely and without further comment. Here the authors prove that sufficiently ample families of traveling‐wave solutions of the doubly infinite system (Formula Presented.) exist in the cases γ > γ_{1} and γ_{1} > γ > γ_{2} for general restoring forces F. In the case with Toda forces, F(x) = e^{x}, the authors prove that sufficiently ample families of traveling‐wave solutions exist for all k, γ_{k} > γ > γ_{k+1}. By a general result proved in Part I, this implies that there exist time‐periodic solutions of the driven system (i) with k‐phase wave asymptotics in n of the type (Formula Presented.) with k = 0 or 1 for general F and k arbitrary for F(x) = e^{x} (when k = 0, take γ_{0} = ∞ and X_{0} ≡ 0).
