A Damage Prediction Model for Quantity Loss of Skidded Spruce Logs during Ground Base Skidding in North Eastern Turkey
Nacrtak In Turkey ground base skidding method is frequently used to extract log material. Physical damages occurring on the skidded log during ground based skidding cause quality and quantity loss of the log. This damage is formed by the ground structure, mass of transported logs, friction coefficient and skidding distance. In this study to improve a »Damage Prediction Model« means to predict t...
متن کاملOptimum road spacing of ground based skidding operations in Nowshahr, Iran
The optimum road spacing has been studied by many researches. It is an important step of forest road network planning. The goals of this study are determining the optimum road spacing in Kheiroudkenar forest of Nowshahr in Northern Iran and study of effect of kind of skidder on skidding cost and road spacing. Continues time study method was used to determine the production rate of TAF and Timbe...
متن کاملCharging damage during residual metal overetching
The influence of electron and ion temperatures on charging damage during residual metal ~latent antenna! overetching in high-density plasmas is investigated by Monte Carlo simulations. The tunneling current through a thin gate oxide, electrically connected to the antenna, increases significantly with electron temperature, mainly as a result of changes in plasma current and ion energy distributi...
متن کاملShape of Skidder Productivity Function for Ground Based Skidding System in Caspian Forests
Cut-to-length (CTL) timber harvesting technology currently accounts for approximately 90% of Caspian forests. The technology involves felling, branching, cross-cutting, and then the skidder carries the logs to a landing, where the timber is temporarily stored, sorted and assembled for transportation to the mill. Cut-to-length systems typically require less labor, less access road construction, ...
