Abstract
The torque-based calculation model for digging-resistance of small-scale hydraulic excavator is presented. The simulation model of digging-resistance is built under AMESim environment, and the structural parameters of SWE50 excavator are imported into AMESim and the digging operation is simulated. The parameters gained from the simulation are imported into calculation model, then the correlation between calculation results and simulation results of digging-resistance is obtained, which shows that this calculation model can indicate effectively the dynamic process of resistance during digging operation and is better than the empirical formula. At last the digging-resistance experiment is operated and the actual resistance is calculated by use of experimental data. The calculation model is proved suitable further for analysis and application of the actual digging-resistance.
