Abstract
A dynamic friction experimental device includes a base, an incident bar, an axial compression device, and a torque loading device. The base is provided with a displacement-constrain structure, and the incident bar includes a first incident section and a second incident section. The first incident section is arranged adjacent to the displacement-constrain structure, and the second incident section is connected to the first incident section. At a joint of the first incident section and the second incident section, a projection of a cross section of the first incident section is positioned in a cross section of the second incident section along an axial direction of the second incident section. When the dynamic mechanical property of a specimen is tested, the axial compression device is configured to apply pressure to the second incident section, and the torque loading device is configured to apply torque to the second incident section.
