DETERMINATION OF FOREST SOIL TRACTION PARAMETERS

Maria Walczykova, Jˇzef Walczyk, Mariusz Kormanek

 

ABSTRACT



Wheel tester was adopted to mate with computer data acquisition card. Some physical properties of the forest stand soil, as well as its shear forces caused by the pneumatic wheel were measured. Based on the knowledge of those forces, it was possible to present shear stresses in relation to the soil horizontal deformation and slip against the coefficient of adhesion.

Key words: soil shearing, wheel tester, wheel slip, coefficient of adhesion.
