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.
