Simulation of a tubular cultivator rack of tillage machines under static and dynamic loads

Abstract

Curved tubes of non-circular cross section are widely used in various fields of technology. The change in the planned operating modes of various technological processes is associated with the wear of the executing mechanisms, which is caused by unstable frequencies and amplitudes of oscillations. Thus, the issue of determining the oscillation parameters of these elements becomes more significant. The technique and results of tests for stresses, displacements and frequencies of natural oscillations of a tubular cultivator tine made in the form of a curved tube of various sections (mainly flat-oval with an inverse ratio of semiaxes) in the ANSYS software package are presented, the maximum allowable loads and the effect of a rigid tip on oscillation frequencies are determined.
