Kinematical excitation due to terrain irregularities on the rolling system of the agricultural machines

Abstract

This paper presents the kinematical influences of the rolling way on the response of the equipment in motion. The basic model of the machine consists of a single degree of freedom mechanical system. The kinematical excitation was supposed to have a harmonic shape and to induce into the axle of the rolling body a resistant moment characterized by the amplification factor that can acquire very high values. This study tries to analyze the way a kinematical action induces dynamic behaviour into the traction system of an agricultural automotive equipment in motion over a terrain with strong irregularities.
