Ragulskienė was a scientific supervisor or consultant of more than half of a hundred defended dissertations.

Her research revealed and explained new phenomena of non-linear vibro-impact systems. She created systems which operate on the basis of new principles. The professor generalized her investigations in research monographs and research papers. The research work of the professor generalizes the results of experimental, analytic and computer studies on the basis of which new theoretical problems and new applications of vibro-impact mechanisms and devices were solved. On the basis of the results of the investigations a number of original devices of vibro-impact type were created which were recognized as inventions.

General activities

Ragulskienė translated from English Samogitia: The Unknown in History by French historian Charles Louis Thourot Pichel. She was active in the collection of data for the encyclopedia The Officers of the Lithuanian Armed Forces 1918–1953. She also prepared materials about the history of her native village of Dapšiai.
