A split Hopkinson tie rod device and method for achieving single-pulse loading
ActiveCN120577135Beffective absorptionImprove reliabilityMaterial strength using single impulsive forceHigh energyIncident wave
This invention provides a split Hopkinson bar device for achieving single-pulse loading, comprising an incident bar, a transmission bar, an incident wave-catching unit, and a stress wave generating unit. The incident wave-catching unit includes an incident wave-catching sleeve and an absorbing bar. One end of the absorbing bar is spaced apart from the incident bar flange, and the other end is connected to the absorbing bar flange. The incident wave-catching sleeve is fitted around the absorbing bar, with its two ends respectively fitting against the absorbing bar flange and the incident bar flange. The compressive stress wave generated by the stress wave generating unit is reflected by the incident bar flange to form a tensile stress wave. After loading the sample, a portion of the stress wave is reflected back as a compressive wave and absorbed by the incident wave-catching unit. This solves the problem of multiple reflections and interference in traditional Hopkinson bars, achieving pure single-pulse tensile loading. The device is compact, has high energy utilization, and is suitable for testing the dynamic mechanical properties of materials.
