Special Issue Information

Dear Colleagues,

The rapid development of technology, combined with an increase in the demand for wood and reduced access to cheap labour, has resulted in significant progress in the construction of machines used in forestry in the last few decades. This has resulted in significant progress in the production, acquisition and processing of wood used in forest management. Automation and robotization are concepts that nowadays are often associated with forestry. This Special Issue aims to present the achievements in the field of modern technical and technological solutions that have recently appeared in forest management, with a particular emphasis on automation and robotization.

Potential topics include, but are not limited to, the following:

  • New design solutions in forest machines;
  • Automation and robotization in forestry;
  • Measuring systems for monitoring work, testing forest machines and their performance;
  • Electronics and computer science in forestry and in forest machines.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Forests is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs).

Long-term tracking tests revealed that the adaptive spiral profiling automatic rubber cutter is prone to “knife off” and “knife jumping” states during the cutting process. These issues result in inconsistent skin thickness and poor cutting surface uniformity and can even damage natural rubber trees, leading to reduced yield, disease, and potentially death. This paper presents experimental research on the parameters affecting the performance of the adaptive spiral profiling automatic rubber cutter. It explores the impact of key parameters on cutter performance and establishes a mathematical model relating these parameters to the peel thickness and cutting surface uniformity rates. Through multi-objective parameter optimization, the optimal parameter combination was determined: a cutting speed of 15 s/knife, a blade thickness of 0.50 mm, and a bending angle of 27.5°. In six tests, the average peel thickness and cutting surface uniformity rates were 97.5% and 96.5%, respectively. These results meet national standards, suggesting that the optimized parameters significantly improve the rubber cutter’s performance. The results meet national standards, demonstrating that the optimized parameters improve the peel thickness and cutting surface uniformity. The regression model is reliable and provides a foundation for selecting better parameter combinations for future prototypes. Full article

Many literature sources state that radial ply tires achieve lower rolling resistance values than cross ply tires. From a certain point of view, radial ply tires are gentler on the ground than cross ply tires. The effort was therefore to experimentally verify this statement for two radial ply and cross ply tires similar in shape and size. The work deals with the diagnostics of rolling resistance levels achieved by radial ply and cross ply tires on selected forest soil under the laboratory conditions of a soil test channel. BKT 210/95 R16 Agrimax RT 855 and Özka 7.50-16 8PR KNK 50 were chosen as radial ply and cross ply tires, respectively, and had approximately the same dimensions. The soil in the soil test channel can be characterized as a loamy sand with an average moisture content of 30% and an initial bulk density of 1445.07 kg·m−3. Another monitored parameter was the diagnostics of changes in soil density caused by tire movement in order to assess the degree of soil compaction. From the results of the work, it follows that there is no statistically significant difference between radial ply and cross ply tires in terms of the achieved levels of rolling resistance on the soil. The observed tires also caused intense compaction of the soil in the soil test channel, especially at higher tire pressures and higher vertical loads. The analysis of the results also shows that changes in tire pressure in both tires cause more energy loss and soil compaction than changes in the vertical load. Full article
