Description
Technical field
The present invention relates to a kind of pneumatic type imitation (big gun) and launch the material impact assay device hit, especially a kind of with sky
Compressed air in press is power, is launched the cylindrical impact that front end is hemisphere or cone to test material by transmitting tube
Material also measures impact bullet speed and the material impact assay device of energy in terms of photoelectric velocity measurement.
Technical background
Material impact intensity is the ability of material opposing external shock.Material or parts are in preparation or the process of use
In, inevitably by various impact External Force Actings, thus material or parts are produced certain damage.Ratio
As, body of a motor car or the airframe of metal material (such as aluminum or steel) can be occurred depression or perforation to destroy by hard thing impact, shadow
Ring automobile or the outward appearance of aircraft and intensity.Composite material quality (uses lamination, the method molding of hot pressing, does not has in a thickness direction
Having reinforcing material, interlaminar strength is low, and composite is more sensitive to percussion, is easy to appearance and damages after by foreign object impact
Wound or delamination failure) body of a motor car or airframe when being impacted by hard thing, sometimes at body of a motor car or aircraft fuselage skin
It is good at finding damage, but in composite inner, layering or cracking can occur so that the intensity of composite is greatly reduced, right
The overall destruction of composite structure and inefficacy define potential threat.Therefore, material is carried out impact test be exploitation with
Application new material or an important content of parts.
Impact strength for mini standards (cuboid or tabular) material sample is tested, and Charpy can be used to try
Test machine or fall-ball type shock machine is tested.For Charpy impact machine tester, due to by pendulum striking edge shape and number
Quantitative limitation, it is difficult to situation when test material is impacted by variously-shaped alluvium.For fall-ball type shock machine, due to
Limited by steel ball number, support height i.e. steel ball free falling bodies height, it is difficult to test material is by various energy, special
It it not situation during super large energy impact.And, when using them that material is carried out shock-testing, pendulum or steel ball are all to hang down
Directly the angle in test sample is impacted.But when material is by real impact, angle of attack has a lot, right angle is wherein
One of.All can not carry out for the impact test of other angle, Charpy impact machine tester or fall-ball type shock machine.
What is more important, for heavy section material samples or the impact test of special-shaped parts, Charpy impact machine tester or fall-ball type
Shock machine is all difficult to owing to limiting by equipment size and impact principle.Therefore, a kind of easy and simple to handle, merit of exploitation
Material or parts, particularly the carrying out of heavy section material samples or special-shaped parts are rushed by material impact assay device that can be complete
Hit test significant.
