Abstract
The article presents a methodology for a reasonable choice of parameters of a machine for collecting of logging waste, which allows to determine the possibility of the machine’s movement depending on various design parameters and natural-production factors when performing technological operations based on an assessment of the traction and coupling properties of the base chassis. A relationship has been established to determine the resistance force to dragging of logging waste, which takes into account the taxation characteristics of the plantation (liquid stock, species composition and density of wood), the parameters of technological equipment (its width) and the peculiarities of the location of the shafts of logging waste through the average distance of passes. The results of determining the resistance force of overcoming a stump with a tooth of technological equipment of a rake type are also given. The proposed nomograms allow, based on the specified operating conditions, to determine the total force of resistance to movement from technological equipment and branches. From this value, using the graphical-analytical method, based on the type of soil, the considered layout of the base chassis and the expected speed of operations, the minimum required engine power, tangential force thrust and weight of the base chassis are established. Based on the results obtained, recommendations are given on the use of various types of base chassis, depending on the type of soil.
