Drag Reduction Performance Parameter Optimization of Vibration Digging Shovel

Abstract:

In order to optimize vibration digging shovels drag reduction performance parameter, building the regression model of traction resistance between vibration frequency and amplitude, penetrating angle and the traction rate based on the vibration reduction simulation experiment results, moreover, it is optimized. The results show that the effect factors of traction resistance from high to low is the vibration frequency, the traction rate, penetrating angle, amplitude. When the drawing speed is 0.67 m/s, the vibration frequency is 13.77 Hz, vibration amplitude is 11.93 mm, penetrating angle is 8.35 °, optimization value of traction resistance is 1449.59 N. Test results show that: the field test resistance average and the simulation results error is less than 5%, which illustrate that the regression model can better reflect the relationship between the vibration frequency, traction rate, penetrating angle, amplitude and traction resistance.
