The predominant forest harvesting method used in northern Europe is cut-to-length logging (CTL). CTL is based on a two machine solution – a harvester is used for felling, delimbing and bucking trees and a forwarder carries the logs from the harvesting area to a roadside loading area where they can be picked up by a truck. These are both off-road machines with a frame mounted crane that operate in areas not accessible by conventional wheeled vehicles at low speed. In order to stay competitive, the Swedish logging industry needs to increase productivity by 2% to 3% per year.
“Now that we have validated the ability of Adams to accurately simulate the performance of forwarders, we will be able to evaluate new design alternatives and optimize the performance of concept configurations in a fraction of the time required by the build and test method,” Ismoilov said. “The ability to evaluate more designs in less time will make it possible to optimize the suspension and other components of the vehicle in order to provide higher productivity without causing discomfort to the operator or damage to the soil.”
