Effects of soil conditions on dynamic mechanical parameters for digging machines

To study the effects of soil conditions (soil composition, soil humidity and soil firmness) on the dynamic mechanical parameters (torque and feeding resistance), this research employed the methods of simulating the real working condition, and realized the real_time data recording on the tester developed by the authors. Based on the analyses of the data, the mathematic relation between the influential factors and the drill's dynamic mechanical parameters was derived and a close curve equation was worked out. The paper obtains the optimal values of the parameters and therefore lays a theoretical foundation for the design, selection and application of digging machines.
