The invention relates to a dynamic test system for the micro-scale charge detonation pressure, which comprises a small explosive container, wherein the small explosive container is pasted to an alignment device; the alignment device enables a spiral copper-manganese film ultra-high pressure sensor, a micro-scale charging body and a PCB adapter plate to be aligned; an input end of the micro-scale charging body is connected with a trigger end of a multi-channel high-speed synchronous pulse constant current source, the trigger end of the multi-channel high-speed synchronous pulse constant currentsource is connected with an input end of an oscilloscope through a coaxial cable, an output end of the multi-channel high-speed synchronous pulse constant current source is connected with an input end of the spiral copper-manganese film ultra-high pressure sensor, an output end of the spiral copper-manganese film ultra-high pressure sensor is connected with the input end of the oscilloscope, andan output end of the oscilloscope is connected with an input end of a computer; the area occupied by a sensitive element is within the range of a circle with the diameter being 0.2mm; and a base of the spiral copper-manganese film ultra-high pressure sensor, the alignment device and an object stage of the small explosive container adopt the same organic glass. The dynamic test system realizes accurate measurement for the detonation pressure of micro initiating explosive devices.
Description
technical field [0001] The invention belongs to the technical field of detonation pressure measurement, and in particular relates to a dynamic test system for microscale charge detonation pressure. Background technique [0002] With the development of miniaturization of weapons and ammunition and miniaturization of pyrotechnics, the testing technology of detonation pressure of micro-scale charge has become an urgent problem to be solved. In the existing micro-scale charge detonation pressure dynamic test system, firstly, there is no alignment device that will cause a large error in the micro-scale charge detonation pressure test; secondly, the material during the detonation shock wave propagation process Impedance mismatch will also lead to certain burst pressure calculation error; again, the analog signal output by the sensor will be distorted due to the mismatch of the characteristic impedance of the transmission line during the electrical signal transmission process. The...
