3. 2. The design of a hydraulic equalizer bar for the feeding mechanism on forest harvester heads

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Arvid Söderlund; [2023]
   Keywords : Harvester; Harvester head; Komatsu Forest; Hydraulics; Equalizer bar; Parallellstag; Stag; Skogsmaskin; Skördare; Aggregat; Skog;

   Abstract : Due to the importance of a correct tree placement and the wear that occurs to equalizer bars inharvester heads, Komatsu Forest AB in Umeå was interested if the bar could be replaced with ahydraulic system. According to Komatsu, the problems were that the equalizer bars that are responsible forsynchronizing the delimbing knives and feeding mechanism add weight, take up space and have atendency to break before their life expectancy.

4. 3. Forest regeneration and edge effects : an ecophysiological analysis after gap-cutting

   University essay from SLU/Dept. of Forest Ecology and Management

   Author : Tyra Tornberg; [2023]
   Keywords : Regeneration; Edge effects; Edge zone; Continuous cover forestry; Gap-cutting; Isotope analysis; 15N; Nitrogen; Carbon;

   Abstract : As continuous cover forestry is an ongoing topic in todays forest debate, questions are raised about eventual issues connected to the management. It is known that seedling performance can be poor near the edge of harvested areas, and around retained trees. This is a critical issue in transitioning toward continuous cover forestry. READ MORE

5. 4. The Effects of Clear-Cutting a Hemiboreal Forest on Local CO2 Fluxes in Norunda, Sweden

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Mads Carlsen; [2023]
   Keywords : CO2 flux; Clear-cutting; Coniferous forest; Flux footprint; Sustainable forestry; Earth and Environmental Sciences;

   Abstract : As CO2 builds up in the atmosphere causing global climate change (IPCC, 2022) trees have become an international symbol of combatting this, and for good reason. Trees take up CO2 which as a result combats these changes, and when these trees are cut down fewer individuals remain to take up the CO2 that we humans emit (Chapin et al., 2011). READ MORE

6. 5. Hanging Load Mock-Up For Experimental Setup To Test Flight System Stability

   University essay from Uppsala universitet/Signaler och system

   Author : Anthony Gundstedt; [2023]
   Keywords : drone; hanging; variable length; mixer matrix; PID; controller; microcontroller; RC; Telnet; I2C; FrSKY; Sbus; S.bus; Forestry; AirForestry; Swing; anti-swing; IMU; filter;

   Abstract : Can we reduce disturbance, swing, and errors by delegating some of the tasks to a subsystem on the tool hanging from a drone to gain precision and dependability? This project covers developing and implementing a user-controlled prototype with an automatic control system and gripper for functionality and controlled movement in 5 DOF. AirForestry is developing a new way of working in the forestry business to provide a greener and healthier solution for the soil and the environment. READ MORE
