Algorithm for constructing the geometry of movement of special vehicles
Abstract.The current problem of the lack of an algorithm for constructing the movement of special vehicles is considered in the paper. The aim of the research is to develop a software package for calculating the rotation of a multi-link special vehicle, taking into account an algorithm that describes the characteristic features of the movement of special vehicles.An increase in the dimensions and mass of long cargoes necessitates the creation of new designs of special vehicles, the distinguishing feature of which is multi-linkage and long-wheelbase, which in turn reduces maneuverability and requires taking into account the peculiarities of movement along a curve.To study the process of moving special vehicles, a geometric modeling method was used to develop an analytical geometric model for the rotation of the tractor and semitrailer. Based on geometric modeling, a method for determining the turning characteristics of a multi-link vehicle has been developed. It has been shown that patency of special vehicles is no less important in comparison with durability, the law of changing the ratio of steering angles of the steered wheels, different axles should provide the maximum turning moment at the maximum steering angles of the front steered wheels, and should also ensure equality of wear at small angles.
