Development of a mathematical model of the oscillatory system of agricultural mobile power equipment with attachments for the creation of their adaptive springing systems

A mathematical model of oscillations of a mobile energy means (MEM) is presented and investigated. The proposed MEM oscillation model makes it possible to determine the positions of the MEM center of mass points in various situations on a support base (agrophone) with a different microprofile. Differential equations have been compiled for computer simulation. The solution of differential equations describing the oscillations of the MEM during its movement in a compound with attachments, as well as a computational experiment-simulation modeling were performed in the software complexes Mathcad and MATLAB Simulink. The initial data used are the mass-dimensional and elastic-damping properties of the structural elements of the MEM, based on the TK-3-180 tractor, obtained by calculation and experiment and a real support base (agrophone) with a known micro- and macro profile. The model makes it possible to study the dynamic processes of the oscillatory system “Support base (agrophone) – running system – machine frame with attachments – cab”. The results of computer simulation modeling are presented – graphs showing fluctuations of sprung and unsprung masses of MEM when moving on different backgrounds

Substantiation of the range of changes in the elastic-damping and inertial characteristics of the oscillatory system of agricultural MES with mounted technological equipment

This article discusses the issue of substantiating the range of changes in the elastic-damping and mass-inertial characteristics of agricultural mobile power equipment (MES) with mounted technological equipment. Substantiation of the range of changes in the elastic-damping and inertial characteristics of an oscillatory system is an important stage in the design process of various mechanical systems and equipment. In this article, the authors present experimental data necessary for further studies of the springing system and present a study aimed at ensuring optimal operating conditions of the system, minimizing the level of vibrations and vibrations, predicting the behavior of the system in various operating conditions and modes. The article describes the research methods used, presents the results and draws conclusions. The research plays an important role in the design of agricultural MEAS aggregated with various technological equipment
