Abstract
This paper examines a micro pressure-controlled metal diaphragm for parallel double chamber firing. The diaphragm, featuring a positive arch and double X-grooves, bursts under pressure without detachment. The convex side bears more pressure. Key parameters, including rupture pressure and diameter, were calculated using design theory. CEL simulations analyzed pressure capacity and rupture deformation. Experiments verified simulations: concave max pressure was 5 MPa, convex 7 MPa, a 40% difference. This design informs multichamber weapons and high-pressure devices.
