Based on the analysis of scientific works of foreign authors, the main factors influencing the efficiency of the operation of timber tractors with semi-trailers have been identified. A promising design of a fifth wheel coupling with a spring shock absorber for timber tractors with semi-trailers that haul timber in difficult road conditions is proposed. A mathematical model of the movement along a logging road of a logging tractor with a semi-trailer equipped with a fifth wheel coupling with a spring shock absorber has been developed. Based on the developed computer program, a preliminary assessment of the performance indicators of the proposed design of the coupling device was carried out. It has been established that the spring shock absorber of the fifth wheel coupling provides, during braking and acceleration, a decrease in the amplitude of acceleration oscillations between a timber tractor and a semi-trailer with timber in the range from 0.95 to 0.6 m/s2. It was found that in order to reduce unfavorable vibrations of a semi-trailer with timber relative to a timber tractor, it is advisable to use dry friction in a spring shock absorber.
