A Design of Ultra-high Pressure Water Hammer Pulse Test System
In this paper,a set of hydraulic hose pulse test system is designed according to GB/T 41028-2021"Requirements of Aerospace Fluid Systems Impulse Testing of Hydraulic Hoses,Tubing and Fitting assemblies".The system is based on LabVIEW and PLC control,and based on the high pressure pulse loading scheme of valvely-controlled booster cylinder,the ultra-high pressure pulse loading method of proportional amplifier and relay control system proportional relief valve is proposed,which can realize the pulse test of water hammer wave up to 70MPa.
