Description
Technical field
The utility model relates to impulse test technical field.
Background technology
The energy absorption behavior of materials and structures plays a part key to the security after structure is impacted.Impact flexibility is one of important mechanical property of material, is used for weighing material impact resistance and energy absorption capacity.At present the conventional method measuring materials and structures energy absorption has the Hopkinson impulse test of drop hammer type, pendulum, ejection type and improvement.Drop hammer type shock test is impacted to certain altitude free-falling sample by drop hammer lifting, by testing the various mechanical property of sample and deformation process, obtains sample low velocity impact performance and energy absorption characteristics.Existing JLW type drop hammer type shock test its ram hammer of device and pressure head are integrated, and each test promotes and needs very large manpower, and indenter shape requires harsher to impact specimen.In addition, the direct impact specimen of ram hammer, the hammer impacts that liquidates some deviation requirement is higher.The comparatively large and ram hammer free-falling stroke operating difficulties of ram hammer dropping process and guide rail contact energy loss.This impulse test making to carry out on same table apparatus under different condition is very difficult.
Summary of the invention
The purpose of this utility model is to provide a kind of split type falling weight impact test device.
The utility model is a kind of split type falling weight impact test device, include ram hammer assembly 1, frame 2, Vertical Rack 3 and pressure head bracket assembly 4, described Vertical Rack 3 is arranged on level ground, frame 2 is vertically arranged on Vertical Rack 3, frame 2 top is provided with fixed pulley, top is provided with ram hammer assembly 1, and bottom is provided with pressure head bracket assembly 4, and immediately below pressure head, ground is provided with sample bench 6.
The utility model and the prior art useful effect had that compares is: ram hammer and pressure head are divided into two parts by this split type drop hammer impact testing machine, wedge shaped pressure head can be dismantled according to impact needs, both axial impact test can be carried out to tubular member, also radial impact testing can be carried out to tubular member.Steel ball contacts the energy loss reduced in tup dropping process with guide groove.Pressure head directly contacts with sample, ram hammer assembly shock load sensor, with pressure head bracket assembly impact specimen, reduces the ballistic error that ram hammer impact deviation causes, avoids load transducer whereabouts external condition to the interference of load simultaneously.The displacement of ram hammer falling impacts can be controlled by adjusting pad, and ram hammer quality adjusts by plus-minus counterweight.Total compares simplifies, and can carry out axis and radial impact testing.
