Evaluation of loading dynamics and fatigue life for a forwarder half-frame articulation

Abstract

Investigations were performed aimed at increasing the fatigue life of articulated load-carrying structures used in multioperational logging machines. A spatial mathematical model for estimating the loading dynamics of articulated load-carrying structures for the entire set of technological operations of the mentioned machines is developed. An approach to the simulation of a stress-strain state of an assembled structure of articulation is outlined depending on the type of technological operation performed by the machine. The results of the investigation are implemented at forest machinery enterprises in the Republic of Belarus.
