Effects of vibrations

Estimation of the Random Intensity of the Soil Tillage Draft Forces in the Supports of the Working Bodies of a Cultivator

“…However, there is no research that validates the random nature of the interaction process between the working bodies of agricultural machines intended for soil processing and which, based on the validation of the random nature of the stresses of such agricultural machines, recommends the approach to modelling work processes within the theory of random functions (Hajek B., 2015;Knill O., 2009;Kobayashi H., et al, 2012;Leon-Garcia A., 2008). More precisely, regarding the series of experimental recordings that form the subject of the analysis whose results are described in this article, they fall into the category of random vibration systems, for which specific approaches are recommended (Meirovitch L., 1976;Buzdugan Gh., et al, 1982;Lalane Ch., 2002;Sireteanu T., et al, 1981). In mechanized work processes in agriculture, vibration analysis has become very frequent, especially with the increase in the quality of agricultural working, with the emergence of precision agriculture and with automation, digitization and robotization in this field (Gong Y., et al, 2023;Yue Y., et al, 2022;Biriş S.Şt., et al, 2022, Yanovych V., et al, 2022Brãcãcescu C., et al 2014, Geng C.X., et al, 2019Samadi M., et al, 2019), for example.…”
