摘要

摘要通过数学分析，找出了影响链式挖沟机挖掘力和功率的因素。数学分析表明，链式挖沟机的挖掘力和功率受刀具切削速度、刀具切削角度、切削运动与垂直方向的夹角、沟槽深度和宽度、土壤与金属的摩擦系数、土壤粘聚力和土壤比重的影响。现场试验结果表明，对于1.2 m和1.5 m的沟槽深度，理论挖掘力（Ftt）分别比实际挖掘力低4.0 kN和3.5 kN。在沟槽深度为1.2m和1.5m时，理论挖掘功率（Pr）分别比实际挖掘功率低3.8%和2.8%。

Mathematical Prediction of Excavating Force and Power of Chain Type Trenching Machine

Abstract A mathematical analysis was done to find out the factors that affect the excavating force and power of a chain type trenching machine. The mathematical analysis showed that the excavating force and power of the chain type trenching machine are affected by tool cutting speed, tool-cutting angle, angle between cutting movement and vertical direction, trench depth and width, coefficient of friction between soil and metal, soil cohesion resistance, and soil specific weight. The results of field experiments showed that the theoretical excavating force (Ftt) was lower than the actual excavating force by 4.0 kN and 3.5 kN for the 1.2 m and 1.5 m trench depth, respectively. The theoretical excavating power (Pr) was lower than the actual excavating power by 3.8% and 2.8% at a trench depth of 1.2 m and 1.5 m, respectively.
