Abstract
Theoretical formulation and analytical solution of the stability problem of heavy machinery, moving on caterpillar tracks on weak subsoil, is presented in the article. The machine base is treated as a perfectly rigid body. The machine-subsoil interaction problem, considering no-tension contact and elastic-plastic but simplified model of subsoil, is solved in a purely analytical way. The bearing capacity of layered subsoil is the most important entry data, used by the model. Different possibilities of its estimation are examined. Results of the analytic model are compared to those obtained from analogous 3D finite element (time-consuming) simulation done in the previous work of the Authors, showing qualitative and quantitative agreement. The interaction curves for the moments in two directions and weight of the machine are developed. Based on this algorithm of design a working platform for the given machine or assessing limit conditions for exploitation is proposed.
