Dynamic Model and Mechanical Properties of the Two Parallel-Connected CRLD Bolts Verified with the Impact Tensile Test

Figure 8

Mechanical model of double CRLD bolts under the stable impact load: (a) original state of the double bolts; (b) initially elastic deformation stage; (c) structural deformation stage; (d) late elastic oscillation stage under the combined action of the impact load and the elastic force of the shank bar; and (e) late elastic oscillation stage only under the elastic force of the shank bar.
