Abstract
This article discusses a mathematical model of the process of driving pile structures using an impulse driver, which is a device based on the forces caused by the centrifugal force of imbalances. This model is a composition of mathematical models for the operation of an impulse driver, a model for the interaction of a pile with soil. Also, for the first time, the issue of product operation in the presence of belt drive defects, which can violate the ratio of the angular velocities of the unbalances, and leads to a decrease in the asymmetry coefficient, is considered. Gaussian white noise was taken as a model of the belt drive errors. When setting up a numerical experiment, the influence of instability at high speeds on the nature of the immersion and the immersion depth was studied.
