Abstract
The article deals with the problem of loss of stability of a dump truck when unloading on an inclined platform. The main task of the study is to determine the maximum permissible angle of inclination of the site. The analysis of modern methods of solving the problem is given. A mathematical model of a dump truck when unloading on a site with a longitudinal slope is developed. In the case of cargo sticking to the platform, an analytical formula is obtained for calculating the critical angle of inclination of the platform. When the cargo is moving, the procedure of step-by-step change of parameters is proposed. Based on the obtained ratios, a program for calculating the longitudinal stability of the dump truck is compiled. The results of assessing the longitudinal stability of two KAMAZ dump trucks are presented.
