Abstract
The description of the road and natural-climatic conditions for the operation of timber-carrying road trains is given. The main features of logging roads, which are characterized by insufficient infrastructure, are considered. The analysis of the negative consequences of the movement of logging road trains along such logging roads in various natural and climatic conditions is carried out. The dependences of the change in the speed of movement and fuel consumption of a logging road train on the nature of the longitudinal profile of the logging road, the performance of the road train on the distance of hauling timber are given. The patterns of change in the speed of movement and the travel fuel consumption of a logging road train depending on its workload and movement along logging roads with different slope values, as well as road roughness parameters, are analyzed. The influence of road conditions of operation of timber road trains on the reliability of their main units and systems is described. The features of maintenance of timber road trains involved in the process of hauling timber are analyzed. The dependences of the change in the flow of spare parts consumption for maintaining the working condition of cars during the year are considered. The patterns of change with increasing mileage of the KAMAZ-53105 vehicle in the mean time between failures and the coefficient of technical readiness are shown.
