Abstract

Abstract

Based on load technique of gas gun and inertia projecting method, a device is developed to eject water column with desired speed and regular shape for hydraulic impact tests.Referring to piston push technology, this device used a projecting cylinder filled with water to replace piston.Under huge push of gas gun, the cylinder is accelerated and will impact buffer when arriving to desired speed, then water column in the cylinder will be ejected under inertial function because the cylinder suddenlly halts.The cylinder is made of alloy steel of high strength, and can be used again after impacting buffer made of rubber material.Using this device, water column with regular shape(Ø200 mm×1 m)is ejected, and satisfyed requirement of hydraulic impact tests.Ejecting speed is gained by photoelectric measurement method, corresponding to results of theoretic calculation.
