Nacrtak Forest roads are an essential yet costly part of forest management, and optimization methods are important tools for planning road systems to support harvesting. This paper presents a Mixed Integer Programming (MIP) optimization model to design a forest access system consisting of logging roads for trucking and access spurs for skidding. The network designed is hierarchical in the sense...

The results obtained in this article relate to the scientific and technological development of timber industry. main idea is based on possibility concentrating several forest plots designated for felling with different percentages cut components within a single cutting area. On logging site created way, skidding trails were laid, allowing entire range operations be carried out. shape such combi...

This paper proposes the new cascaded series parallel design for improved dynamic performance of DC-DC buck boost converters by a new Sliding Mode Control (SMC) method. The converter is controlled using Sliding Mode Control method that utilizes the converter’s duty ratio to determine the skidding surface. System modeling and simulation results are presented. The results also showed an improved o...

Many tasks examined for robotic application like rescue missions or humanitarian demining require a robotic vehicle to navigate in unstructured natural terrain. This paper introduces a motion control for a four-wheeled offroad vehicle trying to tackle the problems arising. These include rough ground, steep slopes, wheel slippage, skidding and others that are difficult to grasp with a physical m...

Anti-lock braking system (ABS) is an automobile safety system for vehicles which will allow controlling wheels of vehicle and providing safety contact on road surface according to driver braking input, avoiding uncontrolled skidding and also preventing the wheels from locking up. The main task of ABS is to press and release the brakes almost 15 times a second, so process of stopping the vehicle...

Machine traffic and timber skidding significantly affect the soil surface and soil properties. The effects are mostly negative and result in soil erosion, worsening of soil properties and inhibition of the growth of roots and soil organisms. In this study, we evaluated forest soil damage caused by the HSM 805 HD wheeled skidder during timber skidding in selected forest stands in the School Fore...

The current study used the improved fuzzy analytic hierarchy process to construct a sustainable deforestation development evaluation system and evaluation model, which has refined a diversified system to evaluate the theory of sustainable deforestation development. Leveraging the visual image of the system dynamics causal and power flow diagram, we illustrated here that sustainable forestry dev...

The objective of this research was to assess the effect of skidding machinery on soil physical and micromorphological properties. The different positions (control or non-traffic areas, left wheel track, right wheel track and log track) and two soil depths (0 10 and 10 20 cm) in three repetitions were investigated. The results showed that average soil dry bulk density in four positions and two s...

Nacrtak Roadside chipping is a common harvesting system in Australian plantations, which utilizes a mobile chipper stationed at the field edge to produce high-quality pulp chips for export. The studied harvesting system included a feller-buncher, two grapple skidders, a flail-debarker and a disc chipper. The study goals were to determine machine productivity, operation costs, fuel consumption, ...
