dc.description.abstract Terenul natural utilizat în umplutură, în terasamentul căilor de comunicații, este caracterizat de următorii factori: umiditate, porozitate, compactitate. Pentru anumite valori ale factorilor ce descriu starea pământurilor, se remarcă o anumită comportare a terenului sub acţiunea forţelor exterioare aplicate prin mijloace mecanice static sau dinamic. În această lucrare sunt prezentate rezultatele simulării numerice a interacțiunii compactor-teren pe baza modelului reologic complex și neliniar, propus de autor în rezultatul elaborării lucrării de cercetare, care ține seama de caracteristicile reale ale terenului (elastice, disipative și plastice) și de cele ale utilajului de compactat (cu un singur rulou vibrator). Modelul a fost armonizat și acordat în conformitate cu rezultatele obținute la prelucrarea datelor experimentale. Pentru simularea modelului a fost utilizat pachetul software specializat Matlab (Simulink, SimMechanics). Rezultatele obținute au evidențiat comportarea reală a utilajului și acțiunea sa asupra terenului supus compactării. The natural soil used in filling the embankment of the road communications is characterized by the following factors: humidity, porosity, toughness. For certain factor values that describe the soil state is distinguished a certain soil behavior under the influence of the external forces applied through static or dynamic mechanical means. In this study are presented the numeric simulation results of the soil-compactor interaction based on the complex and nonlinear rheological model proposed by the author in the result of the elaborated doctorate thesis, that follows the real soil characteristics (elastic, dissipative and plastic) on those of the compaction equipment (with a single vibrating roll). The model was harmonised and granted in accordance with the results obtained from the processing of the experimental data. For the simulation model was used the specialized software package Matlab (Simulink, SimMechanics). The obtained results revealed the real behavior of the equipment and its action on the compacted soil. en_US
