Data set for the article: Analytical model of duckfoots draft force prediction based on soil parameters and technical tools, and its validation in laboratory conditions

It was hypothesized that the developed mathematical model, which takes into account dynamic soil interactions and nonlinear soil-tool interactions, would allow for more accurate prediction of forces in a 2D system under various soil conditions than existing models. The dataset represents the results of soil bin tests, which were used to validate the model. The dataset includes results of force components acting on duckfoot tools with widths of 105, 133, and 202 mm, combined with S and Vibro Crop (VCO) spring tines with stiffnesses of 5.3 and 8.3 kN m–1, respectively. Experiments were conducted in a soil bin filled with loamy sand with moisture contents of 10% and 14% and a compaction of 486 kPa, with duckfoot depths of 30, 50, and 70 mm, and operating speeds of 0.84, 1.67, and 2.31 m s–1. Predictive draught forces were calculated taking into account the determined optimal values of the internal soil friction angles, external soil-tool friction angles, and tool settings using the Solver module in MS Excel. Individual Excel columns are labeled consistently with the list in the article, making the spreadsheet easier to follow. Both Excel files are linked.

File organization: There are two coherent files:
Models.xlsx,
Models-figures.xlsx,
and one auxiliary file: SingleTineForces-R2_DL.xls.

The Models.xlsx and Models-figures.xlsx files are interconnected, and in this case, the Models.xlsx file appears first in the data analysis.
