Computational Modeling of Dynamic Behaviour of Tractor

Abstract

This work deals with the assessment of the effects of a rear-mounted mower on tractor dynamics. The first part summarizes knowledge of the used tractor suspension variants and their various modifications. Furthermore, the current possibilities for simulating the dynamics of tractors and the construction of the rear three-point hitch are described. The main part of the work is devoted to the assembly of the multibody model of the tractor with the rear-mounted mower. The correctness of the assembly of the virtual tractor prototype is verified by comparison with the technical experiment on the real tractor. The validated model is further used to analyse various well-defined steady-state and transient driving conditions typical of this set
