“…The results showed that the soil texture parameter was between 1.4 and 1.5, which is higher than the guidelines set by the ASABE (American Society of Agricultural and Biological Engineers) standard, which prescribes 0.45-0.7 for the same draft force. In another study, an experiment was conducted to analyze the effect of implement surface coating on draft force during tillage operations [10]; the results showed that the modification of the furrower tines with an ultra-high molecular weight polyethylene (UHMW-PE) coating can significantly reduce the draft force. However, analytical studies on the influence of tillage depth on draft force and workload have been limited due to the difficulty of measurement.…”

The objectives of this study were to develop a real-time tillage depth measurement system for agricultural tractor performance analysis and then to validate these configured systems through soil non-penetration tests and field experiment during plow tillage. The real-time tillage depth measurement system was developed by using a sensor fusion method, consisting of a linear potentiometer, inclinometer, and optical distance sensor to measure the vertical penetration depth of the attached implement. In addition, a draft force measurement system was developed using six-component load cells, and an accuracy of 98.9% was verified through a static load test. As a result of the soil non-penetration tests, it was confirmed that sensor fusion type A, consisting of a linear potentiometer and inclinometer, was 6.34-11.76% more accurate than sensor fusion type B, consisting of an optical distance sensor and inclinometer. Therefore, sensor fusion type A was used during field testing as it was found to be more suitable for use in severe working environments. To verify the accuracy of the real-time tillage depth measurement system, a linear regression analysis was performed between the measured draft and the predicted values calculated using the American Society of Agricultural and Biological Engineers (ASABE) standards-based equation. Experimental data such as traveling speed and draft force showed that it was significantly affected by tillage depth, and the coefficient of determination value at M3-Low was 0.847, which is relatively higher than M3-High. In addition, the regression analysis of the integrated data showed an R-square value of 0.715, which is an improvement compared to the accuracy of the ASABE standard prediction formula. In conclusion, the effect of tillage depth on draft force of agricultural tractors during plow tillage was analyzed by the simultaneous operation of the proposed real-time tillage depth measurement system and draft force measurement system. In addition, system accuracy is higher than the predicted accuracy of ± 40% based on the ASABE standard equation, which is considered to be useful for various agricultural machinery research fields. In future studies, real-time tillage depth measurement systems can be used in tractor power train design and to ensure component reliability, in accordance with agricultural working conditions, by predicting draft force and axle loads depending on the tillage depth during tillage operations.

“…[5][6][7] The modification to the furrowed tines by ultra-high molecular weight polyethylene (UHMWPE) coating can reduce draft force significantly, where the draft force of the UHMWPE-coated tine measured 29% less than that of the steel tine. 4 The soil sticky limit was defined as the minimum moisture content where the soil started to show adherence to steel spatula. 8 McFarlane and Tabor 9 demonstrated that surface tension between moisture and water-engaging implements played a dominant role in adhesive force.…”

The phenomenon of soil adhesion occurs when soil-tillage implements interact with soil, which often increases the working resistance and energy consumption. It was found that the membranous leaf sheath of rhizoma imperatae can shuttle in soil, owing to not only its own growth force, but also the anti-adhesion function due to the hydrophobicity and special surface texture. In this article, the microstructure and surface wettability of membranous leaf sheath were studied to reveal its anti-adhesion property by testing. The anti-adhesion mechanism of the hydrophobic surface for the static and dynamic state was analyzed. The biomimetic specimens were designed and fabricated using 65Mn steel inspired by membrane leaf sheaths. The hydrophobic surface was obtained on 65Mn steel by the low free energy modification with myristic acid ethanol solution. For comparison, a 65Mn steel sample without modification was also prepared. A linear soil bin filled with clayey soil with the compaction and gravimetric moisture content of 24.5% dry base was constructed to test the soil anti-adhesion properties of biomimetic specimens. In fixed compacted soil with 24.5% moisture content, the weight of adhesive soil on the modified biomimetic surface measured 50% less than that of the control specimens flat plate surface with modification and NO. 10.

Developments in the wind industry reveal intricate engineering challenges, one of them being the erosion on the leading edge of the wind turbine blades. In this review work, the main issues for the wind industry in the experimentation with respect to erosion are examined. After a historical and general overview of erosion, this review focuses on the rain erosion on the leading edge of the wind turbine blades giving prominence to (1) the rain simulations, (2) experimental erosion facilities, and (3) variables to characterise erosion. These three factors have to be improved to establish a research field enabling the prediction of erosion behaviour and providing useful information about how the rainfall affects the leading edge of the wind turbine blades. Moreover, these improvements in the experimentation of the erosion would be a first step to understand and predict the erosion damage of the wind turbine blades. Finally, this review work also will help to cope with experimental investigations and results in the rain erosion on the leading edge with a deeper critical thinking for future researchers.
