Description

Multifunctional trigger device

Technical Field

One or more embodiments of this description relate to explosion test device technical field, especially relate to a multi-functional trigger device that is used for many equipment linkage of explosion test to trigger.

Background

The industrial gas burning explosion, the condensed explosive detonation and the fragment ultra-high speed impact loading belong to three typical nonlinear transient dynamics problems. Wherein the characteristics of air shock wave overpressure and heat radiation accompanied in the process of gas blasting can directly reflect the coupling power effect of the gas shock wave overpressure and heat radiation on surrounding objects; physical parameters such as detonation wave velocity, detonation wave pressure, shock wave overpressure, driving flying speed to the outer layer metal shell and the like contained in the detonation process of the condensed explosive can directly measure the coupling damage effect of the explosive; the initial speed, the speed attenuation and the impact pressure and the impact limit speed on the target in the fragment ultra-high-speed impact loading process can reflect the coupling impact effect of fragments. Because these three types of tests often have the characteristics of high temperature, high pressure, high transient state, high cost and the like, the accuracy and the repeatability of test data are often very severely challenged. At the moment of gas ignition, explosive detonation or fragment impact electromagnetic excitation, the data information acquisition reliability and effectiveness are directly influenced by the triggering synchronization of the tested optical and electrical instrument equipment. For example, when the signals of the shock wave overpressure and the fragment speed are collected, the optical and electrical testing devices (such as auxiliary facilities like a high-speed camera, a data acquisition instrument, an oscilloscope, a flash light source and the like) are triggered synchronously, so that the condition that the initial triggering time of the testing device is consistent when the ignition, the detonation or the electromagnetic excitation is carried out can be ensured, 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 propagating to a certain specific distance can be calculated, or the impact speed of the fragment reaching the first speed measuring target can be calculated. Therefore, the collection instructions of the whole process equipment are crucial to the reliable collection of experimental data. Along with the development of scientific technology, related test parameters and devices are increased, the traditional detonating device is single in function, multiple types of test devices cannot be triggered simultaneously, the response time of the existing trigger device is long, and the trigger requirement of the current transient test device cannot be met.

In addition, conventional test data acquisition typically employs a probe-type trigger that turns on or off the target. Conventional probe-based testing generally suffers from the following problems: (1) the trigger probe and the detonator are placed in the combustible explosive gas with extremely high risk and even the toxic industrial gas, and the triggered test device is inconvenient for operators to check when detecting abnormality; (2) when the concentration of the combustible and explosive 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 possibly generated, so that the ignition signal and the trigger signal of the testing device can not be synchronized; (3) in the process of test triggering, the probe is connected with a triggering input port of the testing 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 multi-physical-field coupling information is reduced; (5) the process of test triggering mainly detects the triggering of the testing device, the process does not need to detonate an explosive device, the process of probe test triggering needs two workers to complete in a matched mode, one worker needs to remove the probe from a dangerous area to manually ionize the probe, and the other worker needs to monitor whether the testing device is synchronously triggered or not, so that the labor cost is wasted.
