Prospects for the creation of the adaptive vibration control system for an agricultural mobile power unit

BACKGROUND: In this paper, an adaptive suspension system for agricultural mobile power units (MPU) is presented and studied. The analysis of the features of hardware and software for the creation of an adaptive vibration load control system for a MPU is given. The results obtained on the test bench are analyzed, and the prospects for further implementation of such systems on mobile agricultural machines are determined. The effectiveness of the use of the adaptive suspension system in the creation of highly efficient innovative agricultural mobile machines is shown.

OBJECTIVE: Evaluation of the prospects and problems of creating hardware and software for the adaptive suspension system of agricultural MPUs.

METHODS: Materials on the development of the test bench for the adaptive suspension system, hardware and software features are presented. Methods of field testing, processing statistical data from the bench tests and on the characteristics of microprofiles of roads and fields are used.

RESULTS: Based on the results of computational and experimental studies, it was determined that the hardware and software of the developed adaptive suspension system meet the functional requirements. The adaptive suspension system makes it possible to effectively reduce the vibration activity of MPU structural elements by 20% or more, especially on MPUs’ load-bearing systems. It is determined that this effect can ensure an increase in crop yields of up to 30%. Threshold values of the values of irregularities in the microprofiles of agricultural roads and fields have been determined to improve the efficiency of the adaptive suspension system at high linear velocities of MPU.

CONCLUSIONS: With the given studies, it is found that the development and implementation of the adaptive suspension system with highly efficient hardware, mathematical and control software can significantly reduce the vibration load of structural elements of agricultural MPUs, especially in severe operating conditions and irregularities of microprofiles of roads and fields. The introduction of such a system on modern MPU is the key to improvement of many of functional characteristics of the machine, such as working conditions, pressure on the soil, slipping of the propulsion, increasing the durability of the structure. The results of this development can be used in the creation of innovative wheeled transport-and-technological means of agricultural industry with elements of artificial intelligence, namely in suspension systems and chassis of a complete mobile machine, coupled with an agricultural implement.
