In this paper, the arrangement of picks on the cutting head of the transverse-axis driving anchor machine is analyzed and discussed, and two kinds of arrangement modes, namely sequential arrangement and punnett arrangement are studied. Based on the explicit dynamic analysis program ANSYS / LS-DYNA and the Holmquist-Johnson-Cook model, the contact mechanics characteristics between the pick and the rock are analyzed by using the theory and processing method of contact dynamics, rock mechanics and finite element. The maximum cutting force, average cutting force, cutting specific energy consumption and cutting force variance are obtained. By comparing the two groups of arrangement, it is concluded that the punnett arrangement is better than the sequential arrangement. Using MATLAB software to calculate the spectrum of cutting force, it is concluded that the main frequency is between 0 ~ 10Hz when the cutting head works.
