Problems solved by technology

[0003] At present, the impact testing machines on the market are all in the form of free fall impact and bottom excitation impact. The quality of the equipment tested by this type of impact testing machine is relatively small. At the same time, the collision energy dissipation of the system is large, and the acceleration response waveform is uncontrollable. Smaller, the test requirements for civilian equipment are acceptable, but it is far from meeting the requirements for some military equipment tests
For this reason, some military equipment often needs to carry out strong explosive impact tests. This test method is greatly affected by the test site, weather factors, personnel operations, etc., and requires a large amount of manpower, material resources, financial resources and other resources to match, and also has certain advantages. dangerous

Abstract

The invention relates to a high-speed strong impact testing machine which comprises a workbench, an impact table, a lifting device, a rack, a top plate, a first acceleration device and a second acceleration device, the rack and the top plate are connected through a guide column. The guide column is further connected with a workbench and an impact table. One end of the lifting device is arranged onthe top plate; the other end of the lifting device can be connected with or make contact with or be separated from the workbench, one end of the first acceleration device is arranged on the top plate, the other end of the first acceleration device can be connected with or be separated from the workbench, one end of the second acceleration device is arranged on the rack, and the other end of the second acceleration device can make contact with or be separated from the impact table. Three impact effects of light impact, medium impact and high-strength impact can be achieved.

Description

technical field [0001] The invention relates to the technical field of impact testing machines, in particular to a high-speed strong impact testing machine. Background technique [0002] Shock widely exists in engineering. Whether it is packaging technology, vehicle manufacturing engineering, weapon system development or spacecraft product development, the role and impact of shock must be considered. Therefore, in the process of R&D, manufacturing and use, various targeted impact tests are required to assess and ensure its reliability and structural integrity under different impact environments. [0003] At present, the impact testing machines on the market are all in the form of free fall impact and bottom excitation impact. The quality of the equipment tested by this type of impact testing machine is relatively small. At the same time, the collision energy dissipation of the system is large, the acceleration response waveform is uncontrollable, and the response peak value...
