Analysis of Dynamic Response Mechanism of Roadway Bolt

Figure 7

Law of the bolt axial force response with frequency. (a) Axial force at different frequencies (20–160 rad/s). (b) Axial force at different frequencies (160–300 rad/s) (c) Peak value of axial force in different sections (20–160 rad/s). (d) Peak value of axial force in different sections (160–300 rad/s).
