Abstrakty
In this paper, the authors present an extension of the scope of the previously conducted research to the full three-dimensional computer simulation (using the finite element method), which takes into account the interaction between: heavy caterpillar tracks system – working platform – weak subsoil. The article presents a computer model considering two caterpillars, resting on elastic-plastic sub-soil, with standard Mohr-Coulomb yield conditions, allowing for computer simulation of the behavior of the system up to achievement of ultimate limit state. The results of the above model are treated as the reference for a simplified Analytical Models of estimating the limit state, which might be used in design procedures. In turn, these Analytical Models are enhancements of previously presented one. The most important results concluding form the Analytical Model are simple interaction formulas, in the space of moments acting on the machine-subsoil system, limiting a domain of safety in given soil conditions.
W artykule autorzy przedstawiają rozszerzenie zakresu dotychczas przeprowadzonych badan o pełną trójwymiarową symulację komputerową (metodą elementów skończonych), która uwzględnia interakcję między: gąsienicowym układem jezdnym – platformą roboczą – podłożem gruntowym. W artykule przedstawiono model komputerowy uwzgledniający układ jezdny dwóch gąsienic maszyny budowlanej znajdujących się na podłożu gruntowym, sprężysto-plastycznym, przy warunkach plastyczności Mohra-Coulomba, pozwalający na komputerową symulację zachowania się układu aż do osiągniecia stanu granicznego nośności. Wyniki powyższego modelu komputerowego traktuje się jako odniesienie dla uproszczonych Modeli Analitycznych szacowania stanu granicznego, które mogą być wykorzystane w procedurach projektowych. Najważniejszymi wynikami wynikającymi z Modelu Analitycznego są proste krzywe interakcji, w przestrzeni momentów działających na układ gąsienicowa maszyna budowlana – podłoże gruntowe, ograniczające zakres działania przy danych parametrach podłoża gruntowego.
