Abstract

The invention discloses a testing system and a testing method for energy loaded on an initiating explosive device. The testing system comprises a stress wave conversion module, a signal conversion module, a signal amplification module and a processor which are sequentially connected together. The method comprises steps as follows: stress waves generated on an incidence rod and a transmission rod are acquired and converted into resistance signals; the resistance signals are converted into voltage signals of corresponding stress waves; after the voltage signals are amplified, and voltage amplification signals are acquired; time for loading energy on the initiating explosive device is calculated according to time start of generation of stress waves on the incidence rod and time start of generation of stress waves on the transmission rod; the stress waves loaded to the initiating explosive device are calculated according to the voltage amplification signals corresponding to the stress waves on the incidence rod; and energy loaded on the initiating explosive device is calculated according to the time for loading the energy to the initiating explosive device and the stress waves loaded on the initiating explosive device.

Description

technical field [0001] The invention relates to the technical field of detection, in particular to a test system and a test method for energy loaded on explosive products. Background technique [0002] Initiating explosive devices, also known as fire tools, are widely used in military projects such as strategic missiles, nuclear weapons, and aerospace systems. Whether the quality of pyrotechnics meets the specified standards must be tested and analyzed for its safety and reliability before it can be verified or evaluated. The input energy of pyrotechnics is an important performance of its safety and reliability. At present, only the sensitivity of batches of mechanical pyrotechnics can be detected, and the sensitivity of individual pyrotechnics cannot be measured. Contents of the invention [0003] Aiming at the above-mentioned deficiencies in the prior art, the test system and the test method for the energy loaded on the pyrotechnic product provided by the present invent...
