Dynamical and Mathematical Modelling of the Working Process of the Pressing Mechanism of the Hay and Straw Baler Machine

Abstract

In this paper the working resistance of the pressing mechanism is presented by means of specific relations, allowing their introduction as disturbing factors within the mathematical models of the system tractor functioning – namely the hay and straw baler. After the completion of the dynamical model of this system, the next stage was to write a mathematical model by means of which the dynamic solicitation level in the elements of the pressing mechanism and in the components that ensure motion transmission could be assessed. Solving the mathematical model in multiple versions has been achieved with the Runge-Kutta method of integration. Experiments have validated both the proposed mathematical model and the method to solve it.
