AbstractThis study was conducted to investigate the effect of circumferential angle, lug spacing and wheel slip on forces produced by a cage wheel. Experiments were conducted in a laboratory soil bin having Bangkok Clay soil with 51 %(db) soil moisture content. Six ring-type loadcell were used to measure the soil horizontal, ve1tical and transverse reaction on the cage wheel lugs. The circumferential angles were varied from 0°, 15°, 30° to 45°. The lug spacing and wheel slip were varied form 20°, 30° to 40° and 20%, 35% to 50%, respectively. All of force measurements were done at a constant 7 cm sinkage. The results showed that the changes of circumferntial angle up to 45° can reduce variation in pull and lift forces, at the same time it had no effect on the mean of them. The side force and its variations were affected by the changes of circumferntial angle. The 20° lug spacing not only gives the minimum variations but also maximum mean lug forces. The highest lug wheel forces occurred at 35% wheel slip.
