Dynamic Analysis of High Frequency Vibro-Impact Drilling

Vibro-impact drilling system modelling is a research and results of the selected models which is more complex model known as three mass model. As we know that this model is invented to prove the dynamic relationship between the drilled formation and drill bit. The static force, excitation frequency and the excitation amplitude is the main three main control parameters. The investigation ensures that rate of progression is varied by the three main parameters. Higher the static force and excitation amplitude, the best progression rate can be achieved. Thus, in this case, the static force is linear with excitation of amplitude. However, the lower value of excitation and increases in excitation of frequency with the decrease in static force, the result shows zero progression rate. Thus, this concludes the zero progression rate at higher excitation frequency for this models. As based on analysis, the model uses the resonance enhanced drilling (RED) technique for forming resonance state by using the adjustable high dynamic stress to improve the rate of progression. The simulation for the vibro-impact drilling motion is obtained by solving the equation of motion using MATLAB software.
