摘　　要：利用禽蛋定向运动综合试验台,研究同形状塑料卵形体不同质量对其定向运动的影响,以及塑料卵形体、铝质卵形体、洋鸡蛋和鸭蛋定向运动的差异。结果表明:卵形体质量对其轴向运动的水平偏转角和单位时间轴向位移无明显影响,对其翻转运动的翻滚距离和导向杆作用距离无明显影响;非禽蛋卵形体定向运动规律与禽蛋相似。轴向运动稳定阶段4种卵形体水平偏转角和单位时间轴向位移大小顺序均为洋鸡蛋>塑料卵形体>铝质卵形体,而鸭蛋与塑料卵形体相近;翻转运动的翻滚距离和导向杆作用距离大小顺序均为鸭蛋>塑料卵形体>铝质卵形体,洋鸡蛋与铝质卵形体相近;翻转运动的侧偏角大小顺序为铝质卵形体>鸭蛋>塑料卵形体>洋鸡蛋。The effects of mass on the automatic orientation motions of the plastic ovoids with the same shape, and the differences between the orientation motions of the ovoids and the real eggs were studied by using the test device of mechanical orientation motions of eggs. The results showed that, there was no obvious effect of mass on the axial and the turnover motions of the plastic ovoids with the same shape. The regulations of the axial and the turnover motions of other ovoids were similar to that of eggs. In the stable period of the axial motion, the sequence of the deflection angle and the axial displace ment in unit time were both hen egg 〉 plastic ovoid 〉 aluminum ovoid, and the deflection angle and the axial displacement in unit time of duck egg were similar to that of plastic ovoid. The sequence of the rolling distance of ovoid and the action distance of guide rod of the turnover motion were both duck egg 〉 plastic ovoid 〉 aluminum ovoid, and that of hen egg was similar to that of alarninum ovoid. The sequence of the side-slip angle of the turnover motion was aluminum ovoid 〉 duck egg 〉 plastic ovoid 〉 chicken egg.
