Modal Analysis and Numerical Solution in Cable Drilling System
Cable percussive drill is an important drilling machine in the construction of large diameter pile foundation, and complicated dynamic system. However, the design of cable percussive drill is mainly relied on empirical methods or simplified formulas, the dynamic characteristics of coupling system has not been fully understood. Based on the special conditions, the two degrees of freedom dynamic system coupling with buffering mechanism and bit is analyzed, and the vibration differential equation is built. Finally, the modal frequency of system is obtained by numerical method, and the correlation between the modal frequency of system and the structure parameters is built. The result develops the design theory of cable percussive drill and provides valuable preferences for the optimal design.
