Abstract
A single-pulse experimentation device based on a Hopkinson pressure bar and an experimentation method include an experimentation assembly and a pulse controlling assembly, the experimentation assembly includes a power generating mechanism, an incident bar and a transmission bar, a space between the incident bar and the transmission bar is for accommodating a sample, and the sample is for bearing and transferring a dynamic-loading compressional wave transmitted by the incident bar; the pulse controlling assembly includes: a stretching assembly that is internally hollow and is connected to the transmission bar; and an elastic assembly and a gear regulating mechanism that are located inside the stretching assembly, and are connected to corresponding positions of the stretching assembly, respectively; wherein the gear regulating mechanism is configured for driving the stretching assembly to switch between a first position state and a second position state.
