| The aim of this research was to study the effects of soil moisture content and tyre inflation pressure on motion resistance of narrow wheels using a locally developed single wheel test rig. A single wheel Test Rig facility was developed at FUTA. Two narrow wheels of 90/10-10 in width, IRC MB90 tire were used as the test wheels on clay soil. Two inflation pressures of 274 kPa and 380 kPa and 15, 20, 30, and 40 kg load was examined at two different soil moisture conditions (8% and 10% moisture content). R2 value for test wheel 1 with inflation pressure of 270 kPa at 8% moisture content was 0.9974 while that of inflation pressure of 380 kPa at 10% moisture content was 0.9952; also for test wheel two (2) R2 value was 0.9977 and 0.9914 at moisture content of 8%... |

| 農用車輪ラグの運動シミュレーションより得られた, ラグを構成する“前方ラグ面”,“外周ラグ面”および“後方ラグ面”の作用特性の解析結果を実験により検証した。これらの3面に作用する外力を測定するために, ラグ3面用小型トランスデューサを供試して法線方向力と接線方向力を各面別に独立して測定し, この2分力から車輪回転角や供試ラグの角度要素を用いて各面に作用する推進力, 転がり抵抗, 接地荷重反力を求めた。この結果, 前方ラグ面は転がり抵抗と接地荷重反力, 外周ラグ面は転がり抵抗, 接地荷重反力さらに推進力, また, 後方ラグ面は推進力と接地荷重反力を発生しており, 運動解析より得られた結果と一致した。 This research proves the results of the motion analyses of interactions between soil and wheel lug surfaces. Normal and tangential forces acting on the surfaces were measured by small-sized transducers of three-surfaced lug type，and the traction，the motion resistance and the reaction to the dynamic load were calculated with wheel rotational and lug design angles. The results of experiments indicated that (1) the trailing lug side produced the motion... |
