Abstract

In the equipment for simulating explosion waves, the ideal test loading curve can be obtained using high-pressure air drive. To investigate the impact of initial pressure on relevant parameters of shock waves in the test section, AUTODYN16.0 software was employed to simulate the propagation process of shock waves and analyze parameter variations at initial pressures ranging from 100 kPa to 500 kPa. Experimental validation confirms the accuracy of numerical model. The results demonstrate that peak overpressure at the test section outlet ranges from 35 kPa to 111 kPa, with a decrease in energy utilization rate as initial pressure increases. Due to limitations imposed by diaphragm aperture, each parameter’s increase amplitude gradually diminishes when initial pressure is raised by increments of 100 kPa; notably, maximum increase amplitudes occur between an initial pressure change from 100 kPa to 200 kPa.
