Abstract

In this paper, we conduct a mathematical analysis of the model of ensuring the road trains movement stability by changing the design of coupling devices to determine the critical characteristic parameters of the road trains, which result in the loss of en-route directional stability under external action. The concept of the model was to separate the process of yawing of the road trains and its elements (due to external perturbing action) on the highway into several typical stages. The main parameters of the stages (the displacement amplitude and rotation angle of the road trains elements in relation to the driving direction) were determined based on the initial conditions of the road trains movement, the force and duration of the external action. The most dangerous areas of external action application to the road trains were determined in this paper. The maximum permissible exposure limit should not exceed 0.5–1.0% of the road trains trailer momentum, with duration having the greater effect than the amount of impact. The results obtained can be used in mechanical engineering to improve the road trains performance.

Summary

Introduction

Since the use of motor vehicles (MV) and especially road trains (RT) continue to be the main mode to transport all kinds of freight, improving the efficiency of this type of activity (improving performance and reducing accidents on the road) remains a highly topical issue, the solution to which is of great practical importance. It should be taken into account that every tenth road traffic accident (RTA) in Russia involves trucks and RT [1]; in 2019 alone, the number of accidents in Russia was 147738, the number of victims was 189671, including 15158 fatalities [2], etc. F D parameters of RT rTeS sulting in the loss of its directional stability on the road if there are external actions
