Effect of propagation of a reflected shock wave on a pressure field when a detonation wave reflects on an end wall of a tube with opened or closed ignition end

Nihon Kikai Gakkai ronbunshu, 2017
A detonation wave propagating in a straight tube (detonation tube) was reflected off the end wall of the tube, and the pressure profile produced by the propagation of the reflected shock wave was experimentally investigated.

Cryogenic shock tube [PDF]

The Physics of Fluids, 1973
Two shock tubes have been developed which allow for partial or full immersion of the test sections within a cryogenic bath. One tube is used for the study of shock-wave interactions with strong density gradients, and the other to obtain very large shock Mach numbers with ideal gas conditions in all flow regions.

Study on Dynamic Response of Downhole Tools under Perforation Impact Load

Shock and Vibration, 2017
A model of a multibody system is established to investigate the dynamic response of an oil tube-shock absorber-perforating gun system in downhole perforation-test joint operation. In the model, the oil tube and perforating gun are modeled as elastic rods

Cold Forging Effect on the Microstructure of Motorbike Shock Absorbers Fabricated by Tube Forming in a Closed Die

Applied Sciences, 2021
Motorbike shock absorbers made with a closed die employ a tube-forming process that is more sensitive than that of a solid billet, because the tube is usually too thin-walled to conserve material. During tube forming, defects such as folding and cracking

Orifice Plates in a Shock Tube [PDF]

The Physics of Fluids, 1962
This note points out some interesting aspects of a recent study of the flow resulting from the use of area change near the diaphragm of a shock tube. (1) Earlier studies (2,3) have been directed toward the use of area change for increasing the available shock speed, and thus have considered geometries where A4/A1 > 1 and A*/A1 = 1 [see notation on Fig.

Design and Numerical Analysis of a Double-Tube Magnetorheological Shock Absorber for Vehicle Seat Suspension Systems

Gazi Üniversitesi Fen Bilimleri Dergisi, 2019
In scissors-type suspension mechanisms of the driver's seats of vehicles such as tractors, trucks and buses, conventional double-tube shock absorbers are often used as dampers due to the length of the course.
