Abstract
During the operation of a vibratory roller, the vibrations affecting the operator are significant, causing discomfort. This paper presents a dynamic model of a two-drum vibratory roller as a planar model, which takes into account the oscillations of the driver's seat and the elasticity of the ground. Based on the dynamic model, the Lagrange equations of the second kind are used to establish a system of differential equations describing the motion of the mechanical system. The results of the study provide a foundation for evaluating the vibrations affecting the operator under different working conditions and comparing them with ISO standards on acceleration affecting the operator. Furthermore, the paper investigates the impact of the vehicle's center of gravity position on the acceleration experienced by the operator. The findings serve as a basis for further research and improvements to the machine's structure to reduce vibrations affecting the operator while ensuring work efficiency.References
