Abstract

The invention discloses an ignition and detonation velocity synchronous testing device and method, and solves the problems that an existing device cannot synchronously test ignition time and detonation velocity, is easy to fail and has potential safety hazards. The ignition and detonation velocity synchronous testing device is provided with a sample tube, and an ignition unit and a microwave interference unit which are connected with the sample tube, and a signal synchronization device is arranged between the ignition unit and the microwave interference unit. The signal synchronization deviceis provided with a signal input unit and a signal output unit which are in transmission connection through an optical coupler. The signal input unit synchronizes an ignition signal of the ignition unit to the signal output unit through the optical coupler, and the signal output unit sends the ignition signal to the microwave interference unit to send and receive a microwave signal. The device is suitable for synchronous triggering and acquisition of ignition and detonation velocity tests of explosives and powders, and is also suitable for synchronous acquisition of ignition, temperature, pressure, high-speed photography and the like in explosive and powder combustion and detonation experiments.

Description

technical field [0001] The invention belongs to the field of testing instruments, and specifically relates to a device and method for synchronous testing of ignition and detonation velocity, which is suitable for synchronous testing of ignition and detonation velocity of propellant and explosives, and is also suitable for ignition, temperature, pressure, and temperature in combustion and detonation experiments of other energetic materials. Synchronous acquisition and testing of high-speed photography, etc. Background technique [0002] The test and research of detonation performance are very important for the application of new high-energy explosives, and the whole process from the ignition of explosives to detonation is very short. Under the premise of high efficiency, economy and safety, ignition equipment and other test devices are required to be able to Realize synchronous triggering, so as to realize accurate measurement of the detonation process of explosives, provide ...
