Abstract

The invention relates to a test system for the response characteristics of material rotation impact, the system includes (i) rotation and impact unit, (ii) data acquisition unit and (iii) data analysis unit, the invention can be used to test rotation impact and single impact Material properties under pulsed loads such as percussion drilling, rotary-impact drilling and impact effects in rotary drilling and other rotary-impact loads, revealing material structure and strength by testing stress wave signatures in input rods characteristic. Conversely, it can also be used to study the structural shape and material properties of the impact warhead to obtain good incident waveforms and damage effects.

Description

technical field [0001] The present invention relates to a material rotation impact response characteristic test system, a test technology for testing the response characteristics of materials under rotation-impact loads, which can be used for the dynamic strength of materials under different impact loads and different rotation speeds, and The test and analysis of reflection and transmission stress wave peak characteristics and energy characteristics can be used to study the structure and dynamic characteristics of loaded materials; it can also be used to test the impact load characteristics under different impact rates, which belongs to the field of materials and geotechnical engineering. Background technique [0002] At present, in geology, geotechnical engineering and other surveys and mining engineering production, drilling / exploration methods are usually used, and the main drilling methods are percussion, rotary or rotary-percussion. The relationship between the crushing...
