Abstract

The invention discloses a split-type hopkinson torsion bar energy storing and releasing device as well as an operation method thereof, which can realize impact torsion energy storing and releasing bya simple mechanical structure. The apparatus comprises a hopkinson incident bar, a clamping mechanism, a releasing mechanism, and a guiding mechanism. The operating method is characterized in that theHopkinson incident bar is clamped by the clamping mechanism and guiding mechanism, the torque storage is realized, by designing the releasing device, the stored torsion energy is subjected to instantrelease, so that the shock loading effect can be simulated, and the impact experiment simulation condition is provided; and at the same time, the loaded shock loading is determined by torsion turns numbers, which is conveniently controlled; the split-type hopkinson torsion bar energy storing and releasing device is suitable for different loading devices, and is repeatedly usable without materialconsumption. The device has the advantages of simple structure, low cost, easy control, and convenient operation.

Description

technical field [0001] The invention belongs to the technical field of impact torsion experiments, and in particular relates to a separate Hopkinson torsion bar energy storage and release device and an operation method. Background technique [0002] The torsion test is a basic experiment to understand the shear resistance of materials. It is generally carried out on a torsion testing machine. During the test, a torque is applied to both ends of the sample. At this time, a torsion angle will be generated between the two sections of the sample. When the torsion angle reaches a certain level , the specimen will be twisted off, and the fracture morphology of the torsion specimen can reflect the material properties and stress conditions. However, in some working conditions, the material will be subjected to high-speed impact torsional loads, such as the load on the axle when the engine clutch is engaged, and the load on the rotating shaft when the vehicle brakes. When the materi...
