Description
Technical Field
One or more embodiments of the present disclosure relate to the field of explosion testing devices, and in particular, to a multifunctional triggering device for linkage triggering of multiple devices in an explosion test.
Background
The detonation and fragment ultra-high-speed impact loading of industrial gas explosion and condensed state explosive belongs to three typical nonlinear transient dynamics problems. Wherein, the air shock wave overpressure and heat radiation characteristics accompanied in the gas explosion process can directly reflect the coupling power effect of the air shock wave overpressure and heat radiation characteristics on surrounding objects; the coupling damage effect of the explosive can be directly measured by physical parameters such as detonation wave velocity, detonation wave pressure, shock wave overpressure, driving scattering speed of an external metal shell and the like contained in the detonation process of the condensed explosive; the initial speed, speed attenuation and impact pressure and impact limit speed of the target in the process of loading the broken piece by ultra-high-speed impact can reflect the coupling impact effect of the broken piece. Because these three types of tests often have the characteristics of high temperature, high pressure, high transient state, high cost and the like, very serious challenges are often presented to the accuracy and repeatability of test data. The triggering synchronization of the gas ignition, explosive detonation or fragment impact electromagnetic excitation moment and the tested optical and electrical instrument equipment directly influences the reliability and effectiveness of data information acquisition. If the triggering synchronization is carried out on the optical and electrical testing devices (such as high-speed photography, a data acquisition instrument, an oscilloscope, a flash light source and other auxiliary facilities) during the acquisition of the shock wave overpressure and the fragment speed signals, the consistency between the triggering initial time of the testing devices and the triggering initial time of the ignition, the initiation or the electromagnetic excitation can be ensured, so that the acquisition equipment can be accurately triggered to capture the shock wave signals and the initial time of the fragment driving loading process, the peak overpressure of the shock wave transmitted to a certain specific distance can be calculated, and the impact speed of the fragment reaching the first speed measuring target can be calculated. Thus, the acquisition instructions of the whole process plant will be crucial for the reliable acquisition of experimental data. Along with the development of scientific technology, the related test parameters and equipment are increased, the traditional detonating device has single function, can not trigger multiple types of test devices at the same time, has long response time of the existing triggering equipment, and can not meet the triggering requirement of the current transient test device.
In addition, conventional test data acquisition generally employs a probe-type triggering mode of on-target or off-target. Conventional probe testing generally has the following problems: (1) The triggering probe and the detonator are simultaneously arranged in the industrial fuel gas with extremely strong flammable and explosive property and even toxicity, and the triggered testing device is inconvenient for operators to check when detecting the abnormality; (2) When the concentration of the combustible gas is low or the concentration of the injected inert gas is high, the situation that the ignition head can ignite the gas but can not reliably ionize the probe at the same time is extremely likely to occur, so that the ignition signal and the triggering signal of the testing device can not be synchronous; (3) In the test triggering process, a probe is connected with a triggering input port of test instrument equipment, and when unsafe factors of stray current flowing out of the input port cause extremely dangerous potential safety hazards to operators; (4) The trigger probe generally occupies one test channel in the data acquisition equipment, so that the number of Euler test points of the multi-physical field coupling information is reduced; (5) The test triggering process is mainly to detect the triggering of the testing device, the process does not need to detonate the explosion device, the probe type test triggering process needs to be completed by two workers, one worker needs to go to the dangerous area to ionize the probe manually, and the other worker needs to monitor whether the testing device triggers synchronously, so that the labor cost is wasted.

In this embodiment, the stable output time of the synchronous level output signal may be 0.6ms, and the stable output time of the detonation output signal may be 0.1s, that is, the stable output time of the detonation output signal is longer than the stable output time of the synchronous level output signal, that is, the triggering of the testing device is completed before the detonation, which is favorable for the synchronous test of the detonation process.
In another embodiment, the triggering device in the above embodiment is applied to perform a test triggering test, and a response time test of the synchronous level output signal and the initiation output signal from DC0V to the highest output voltage is shown in FIG. 3, wherein the response time of the initiation output signal is 0.02ms. The synchronous level output signal port is connected with a SYV-3 coaxial cable with the length of 50m, the response time of the output voltage of the port rising from DC0V to DC5V is 0.63 mu s, and the data acquisition test device can be reliably triggered at the moment. In consideration of the safety of the test triggering test, the electric ignition head/electric detonator/electromagnetic excitation device is not connected to the detonation signal output port, so that the curve generates certain oscillation in the initial stage after the voltage is increased, and when the output voltage of the synchronous level signal output port is increased to reliably trigger the data acquisition equipment, the voltage of the detonation output port under the condition of the moment can reach DC22V stably.
