Summary: The article addresses a pressing issue concerning the insufficient adaptability of current design parameters of timber truck tractors with trailer links to the operating conditions on forest roads, which are often characterized by poor infrastructure and challenging terrain. The necessity of developing advanced technical solutions aimed at improving the efficiency of timber truck combinations under harsh road conditions was substantiated. The study identified a set of structural, technological, and operational factors influencing the performance of tractor-trailer combinations. To enhance the operational efficiency of the truck combination, a regenerative swivel bunk device with a ball joint was proposed, which improved timber load stability and enabled energy recovery when driving on uneven roads. A mathematical model was developed to analyze the impact of key factors on the performance of this bunk device. The model describes the dynamics of interaction between the truck combination links, the timber load, and the regenerative swivel bunk device with a ball joint under non-steady motion conditions. The research was conducted using specialized software, with a series of computer simulations performed. The simulation results demonstrated that increasing the truck combination’s speed from 5 to 40 km/h led to a rise in recovered power from 5.1 to 16.2 kW, while the lateral displacement amplitude of the timber load decreased from 0.36 to 0.27 m, indicating improved load stability. Additionally, it was found that when road surface irregularities varied within the studied range, the proposed swivel bunk device enabled power recovery from 0 to 86.1 kW, proving highly effective on difficult forest road sections. For forest roads with irregularities of 0.2—0.3 m in height, the lateral displacement amplitude did not exceed 0.322—0.521 m. The obtained results hold significant practical value for further improving the design of timber truck combinations, allowing for optimization of their operational performance and reduced energy consumption during timber transportation. |
