Burd V.Sh., Krupenin V.L. «Almost periodic oscillations in vibroimpact systems» Вестник научно-технического развития, № 3, http://www.vntr.ru/ftpgetfile.php?id=47 (2007)

The presence at anyone vibroimpact system large nonlinear positional forces – it is a reason of clear manifestation in them of various nonlinear effects. Inception of almost-periodic processes – it is one from major and also important such effects and these effect is studied. We have two base models there: resonant systems with one degree of freedom and some systems with the distributed impact elements are considered.
