| Abstract | Experiments were conducted in a laboratory soil bin with Bangkok clay soil to measure the forces in quasi-static condition under model multiple cage wheel lugs. A new soil bin was constructed and developed which enables to produce slip atdifferent levels. The study was aimed to investigate the forces acting on the lugs at lower level of slip. 1 'he transducers were used for measuring the soil reactions on the lugs in both perpendicular anc l radial directions. The force measurements on both lugs were done at constant moisture and sinkage. The lug spacings were varied at 20, 30 and 40 degrees, and slip was varied at five levels: 10%, 15%, 20%, 25% and 35%. The measured perpendicular and radial forces.were converted to lug pull and lift forces. It was observed that the perpendicular and radial as well as pull and lift forces acting on the first lug were higher than that on the second lug. Increase in the slip caused increase in lug forces for both lugs. It is found that the forces on the second lug were more influenced by change of slip. Increase in lug spacing caused increase in the lug forces. Both slip and spacing showed more effect on the second lug. |
