Some Aspects on Modeling of the Moving Forest Machines 2000-01-2629
This paper concentrates on some important aspects, restrictions and problems that should be considered when modelling off-highway vehicles. The main modelling interest is focused on log forwarder machines, see Figure 1 but indicated principles are easily generalize to the other kind of vehicles and machines. The mechanics, hydraulics, hydrostatic propelling system with control system, tire-road-interaction and system interaction were modelled by using ADAMS® (Automatic Dynamic Analysis of Mechanical Systems, ADAMS is a registered trademark of Mechanical Dynamics, Inc.) dynamic simulation software. Also the modelling of flexible parts with lumped-mass approach and assumed modes methods are discussed.
The matters are examined mainly from the point of view of modelling techniques with the ADAMS dynamic simulation software.
