Theoretical study of the influence of a variable ground resistance by position tracked chassis in motion

Abstract

The position of the tracked chassis of a vehicle in motion often determines the accuracy of the creation of related structures during construction and road work. There are technical solutions for chassis positioning systems in several planes, based on laser leveling technologies. These systems implement the tracking principle of monitoring the position of the chassis, reacting to abnormal changes in position. Software implementation of position control based on its prediction during opera-tion is difficult to implement, since it must take into account the influence of many random factors on the movement of the machine (variability of movement resistance forces over time, etc.). This article examines the influence of variable resistance to ground movement on the position of tracked chassis in motion. Specific aspects are shown that characterize the change in the po-sition of the machine depending on the combination of laws of change in the coefficients of resistance to movement under each caterpillar. The examples show procedures for mathematical prediction of the physical and geometric characteristics of the movement of a tracked vehicle, the use of which in software algorithms of posi-tion control systems can help improve the accuracy of their operation.
