Design of high speed Hydraulic impact loading system

Abstract

 In order to research on prestressed anchor cable under different impact load failure mechanism and simulate the cable in the pull off, breaking in the process of friction heat, spark design test system, the design of actuator hydraulic cylinders and auxiliary energy storage device with calculation and analysis of, up to requirements. Then introduced the working principle and control process of the mine anchor impact testing system, focusing on the hydraulic system design and calculation, and a brief description of the hydraulic auxiliary parts of the principle, the function and the characteristic, and carries on the choice list. In the end, the assembly drawing of the equipment can be seen clearly, and the structure and shape of the equipment can be seen clearly. Through the high-speed camera to shoot the changes in the state of the cable, to get the required parameters, complete the test.
