摘要
In this paper, the impact between the hammer and the pole was simulated as a spring whose stiffness is K and whose mass is zero, so as to probe into the local deformation. Then the expression of the impact force and the pulse time during the impact were derived. The results further describe the mechanics of the impact of the hammer and rock bolt and creates the condition for the improvement of the engineering detection quality in the rock bolt nondestructive dynamic detection.
