Aiming at the problem of lack of test equipment for static-dynamic composite loading in studying the mine rock mechanics, and the load-bearing capacity of anti-scour support equipment and energy-absorbing structures, a kind of high-speed hydraulic impact test bench was proposed.It adopted a hydraulic loading form to do impact tensile and impact compression tests for specimens of different structures.Here, the structure and working principle of the test bench were analyzed.3 loading modes of the bench including static loading, impact dynamic one, and static-dynamic composite one were presented.The response characteristics of the bench were analyzed using the software AMEsim.The finite element dynamic analysis for the bench was also conducted with the software ABAQUS.After the prototype was made, anchor rods, etc.were tested.The results showed that the bench’s 3 loading modes are feasible, and the actual working conditions of specimens can be simulated by this loading test system.This bench provided a platform for studying dynamic characteristics of anti-scour support equipment and laid a foundation for further studying ultra-high energy level hydraulic impact test benchs.
