Abstract

The purpose of the research is to determine the conditions for maintaining the course stability of the bulldozer on the caterpillar track (hereinafter referred to as the term "caterpillar") in the process of excavating the soil with the slope board. The paper presents mathematical model of the process of operation of the caterpillar bulldozer with the slope board, taking into account its main parameters: 1) parameters of the slope board and its installation angles; 2) parameters of the base machine; 3) dynamic parameters of the bulldozer with the slope board; 4) parameters of the soil. Based on the developed model, using the computer modelling method in Mathcad Prime 3.0 program, a hodograph of the maximum force applied on the slope board of the caterpillar bulldozer was built, which made it possible to determine the maximum allowable force applied on the slope board, taking into account the retention of the course stability.
