Abstract: (4316 Views)
Determining the behavior of structures under high-speed loading at different applications is very important. One of the most important equipment in this field is a shock tube that can simulate the mentioned objects above in a laboratory environment. The aim of this paper is to investigate the effect of the geometrical parameters of the shock tube on the impulse of the shock wave generated. In this study, the effect of change in outlet diameter with the nozzle and the variation in the length of the driver and driven sections on the wave created in the decrease and increase shock intensity has been investigated. In this regard, the functional components of the 3-inch gas-driven shock tube were investigated on the dynamic deformation of aluminum sheets. Based on the results, the length of the driver is not effective on the peak of the generated wave pressure. However, the driven length effects on the deformation of the sheet, in this way that the shorter the driven length is, the higher the dome height will be. The effect of concentrating the shock wave on the sheet is visible in the samples in which the nozzle is embedded. This demonstrates that a more centralized dynamic load has led to deform the sheet. Also, at high pressures compared with lower pressures, the nozzle effect is better in concentrating the shock wave from the explosion in the shock tube.
