Systems and methods for oscillating a string within a subterranean well include a motor assembly having an output shaft extending along a central axis. A translation coupling is in mechanical communication with the output shaft. An inertia sleeve is in mechanical communication with the translation coupling. The translation coupling is operable to translate a rotation of the output shaft to an oscillating movement of the inertia sleeve. A spring assembly is in mechanical communication with the inertia sleeve. The spring assembly is positioned along the central axis.
