Investigation of the Influence of Permanent Traffic Lane Properties on Rolling of Bridge Agricultural Equipment Wheels

Abstract

Movement of bridge agricultural equipment along the permanent traffic lanes is characterised by significant energy costs for overcoming the rolling resistance forces. Until now, the movement process of bridge agricultural equipment wheels along the compacted soil of permanent traffic lanes has been paid only a little attention. It has been established that the physical and mechanical properties of soil lanes significantly affect the energy consumption necessary for overcoming the rolling resistance of forces of bridge agricultural equipment wheels. Considering the range of possible changes in these properties, the coefficient of rolling resistance of equipment wheels varies from 0.06 to 0.1, which is 66%. In order to reduce the rolling resistance coefficient of equipment wheels when moving along the permanent traffic lanes, the surface needs to be undeformable. When moving along such a solid and dense supporting surface, the wheel rolling resistance is lowest.

Investigation of the Energy Indicators for the Surface Treatment of Soil by a Harrow With a Screw-Type Working Body

“…The work Bulgakov et al, (2022), substantiates the practical possibility and expediency of using a screw-type working body in tillage, and the work Bulgakov et al, (2021) reflects experimental research to determine the quality indicators of a harrow with screw-type working bodies. Works Manjula et al, (2017) Tripathi et al, (2015), Tian et al, (2018) are devoted to the study of the impact of design and technological parameters of the developed variants of a harrow with screw-type working bodies upon the incorporation efficiency of the plant residues into the soil.…”

“…In order to determine the energy parameters of tillage by a harrow with screw-type working bodies, it will be considered in the form of an unfolded helicoid. Then the equation of the surface of the working body of the harrow with an axis parallel to the Ox axis has the following form: 𝑋 = ℎ𝛼 − 𝑢 sin𝜑 𝑌 = 𝑝 sin𝛼 − 𝑢 cos𝜑 cos𝛼 𝑍 = 𝑝 cos𝛼 + 𝑢 cos𝜑 sin𝛼 (1) where: hthe screw helicoid parameter (ratio of helicoid pitch to full revolution), 2 cos b h…”

Study of the Turning Process of the Bridge Type Machines

“…The theory of movement and controllability of wheeled traction-transport machines is sufficiently studied (Nadykto V. et al, 2015;Bulgakov V. et al, 2022;Bulgakov V. et al, 2020;Ivanovs S. et al, 2020;Ivanovs S. et al, 2018;Bulgakov V. et al, 2016;Szakács T., 2010;Bulgakov V. et al, 2021;Fashutdinov M. et al, 2020;Panchenko, A., 2015). The operation of any wheeled machine takes place under conditions of a large number of disturbing factors (forces and their moments) that change the position of the machine in space and deviate its movement from the specified trajectory.…”

“…The steering of most modern wheeled machines is adapted to manual steering and is based on the kinematic or power steering principle (Nadykto V. et al, 2015;Bulgakov V. et al, 2022;Demšar I. et al, 2012;Bulgakov V. et al, 2020;Ivanovs S. et al, 2020;Ivanovs S. et al, 2018;Bulgakov V. et al, 2016;Bulgakov V. et al, 2021). Kinematic steering involves turning the steered wheels (front, rear or both front and rear) relative to the carcass or changing the position of one part of the mobile machine relative to the other in the horizontal plane (articulated frame).…”
