As a promising and convenient numerical calculation approach, the discrete element method (DEM) has been increasingly adopted in the research of agricultural machinery. DEM is capable of monitoring and recording the dynamic and mechanical behavior of agricultural materials in the operational process of agricultural machinery, from both a macro-perspective and micro-perspective; which has been a tremendous help for the design and optimization of agricultural machines and their components. This paper reviewed the application research status of DEM in two aspects: First is the DEM model establishment of common agricultural materials such as soil, crop seed, and straw, etc. The other is the simulation of typical operational processes of agricultural machines or their components, such as rotary tillage, subsoiling, soil compaction, furrow opening, seed and fertilizer metering, crop harvesting, and so on. Finally, we evaluate the development prospects of the application of research on the DEM in agricultural machinery, and look forward to promoting its application in the field of the optimization and design of agricultural machinery.

The authors presented a work that raises the reliability of agricultural machinery, the organization of diagnostic procedures and the effective use of units by reducing downtime. It is proposed to organize the diagnostic process according to the hierarchical principle and use the expert system to analyze the state of the object in the current situation. The diagram of the structure of the diagnostic system using the center of the state analysis is presented. The article is of interest to specialists working in the field of operating grain harvesters and increasing the productivity of agricultural work.

In article possibility of active suppression of vibrations of elements of a design of agricultural machinery is investigated. It is shown that it is possible to achieve the effective suppression of vibrations without the use of complex and expensive technical solutions, complex and time-consuming calculations and without conducting many experiments. The results of experimental research into active vibration suppression are covered.
