The shock wave detection device comprises a switching power supply, a trigger, a pressure probe, a test desk, an oscilloscope, a shock wave generator and a trigger switch. The shock wave detection device has the advantages of stability and reliability, the shock resistant performance of different tubes can be detected, dynamic situations of xenon lamp discharge can be preferably simulated, and the rapid pressure change can be accurately caught.
Description
Technical field
The present invention relates to shock-wave analog verifying attachment, particularly a kind of simulation fluorescent tube bears pressure surge pick-up unit.
Background technology
During high power xenon flashlamp electric discharge, the shock wave of high temperature xenon plasma generation can cause damage to pipe wall material, when serious, even make fluorescent tube material damage, this is the main cause that causes fried lamp, and can the shock resistance of while fluorescent tube material be also related to xenon lamp and use safely and serviceable life.The intensity of load and the pipe wall material that experimental results show that high power xenon flashlamp have close relationship, the one of the main reasons that fluorescent tube destroys under high power discharge condition is that the radial impact ripple of γ-ray emission in lamp bursts tube wall, and this situation is different from static radial tension.Be limited to condition, to fluorescent tube intensity, can only take radially static tension test data in the past, can not simulate flashlamp discharge dynamic situation during operation.
Summary of the invention
The object of this invention is to provide a kind of analog modulation pipe pressure shock-wave detection device, this device can detect the size of different tubing shock resistances, the current intelligence of energy simulate flashlamp discharge.
The technology of the present invention solution is as follows:
A kind of pick-up unit of analog modulation pipe pressure shock wave, special electricity is that this device comprises Switching Power Supply, trigger, pressure probe, test board and oscillograph, glass tube to be measured is placed on described test board, described glass tube Inner to be measured is equipped with pressure probe and tinsel and is full of water, the positive pole of described Switching Power Supply output connects the positive pole of electric capacity and the anode of ignitron, the trigger electrode of described ignitron connects the output terminal of described trigger, the negative electrode of described ignitron connects one end wiry of enforcement, the other end of described Switching Power Supply connects the other end wiry of enforcement through the negative pole of described electric capacity, oscillographic input end described in the output termination of described pressure probe.
Advantage of the present invention:

Embodiment
Below in conjunction with embodiment and accompanying drawing, the invention will be further described.
First refer to Fig. 1, Fig. 1 is analog modulation pipe pressure shock-wave detection apparatus structure schematic diagram of the present invention, as seen from the figure, the pick-up unit of analog modulation pipe pressure shock wave of the present invention, comprise Switching Power Supply 1, trigger 6, pressure probe 12, test board 10 and oscillograph 8, glass tube 11 to be measured is placed on described test board 10, described glass tube to be measured 11 Inner are equipped with pressure probe 12 and tinsel 9 and are full of water 13, the positive pole of described Switching Power Supply 1 output connects the positive pole of electric capacity 2 and the anode 3 of ignitron 7, the trigger electrode of described ignitron 7 connects the output terminal of described trigger 6, the negative electrode 4 of described ignitron 7 connects one end of tinsel 9, the other end of described Switching Power Supply 1 connects the other end of tinsel 9 through the negative pole of described electric capacity 2, the input end of the oscillograph 8 described in the output termination of described pressure probe 12.
Fig. 2 is pressure probe of the present invention scheme of installation in tested glass tube, rubber plug 14,15 airtight sealing are used at the two ends of glass tube 11 to be measured, tinsel 9 is through rubber plug 14 and 15 two ends and keep the stretching state of tinsel, and perforate 16,17 places that tinsel 9 penetrates rubber plug 14 and 15 cover and prevent from leaking with silica gel.In glass tube 11, be full of tap water 13, pressure probe 12 is inserted in the glass tube 11 that is full of water 13 and is maintained a certain distance with tinsel 9.Pressure probe 12 penetrates rubber plug 15 perforate 18 places and prevents from leaking with raw material band sealing.
The principle of work of analog modulation pipe pressure shock-wave detection device is as follows:
2 chargings of 1 pair of electric capacity of Switching Power Supply, while being charged to a certain voltage, the pulse signal that trigger 6 sends makes electric capacity 2 by tinsel 9 electric discharges in 7 pairs of water 13 of ignitron, peak pulse electric current is vaporized and is produced shock wave by tinsel 9, utilize the incompressibility of water, this discharge impact ripple is passed to glass tube 11 fast from tinsel 9 positions, pressure surge is delivered to pressure probe 12 places by water 13 simultaneously, tourmaline crystal in pressure probe 12 converts the pressure signal of experiencing to electric signal, and its pressure waveform is presented on oscillograph 8.The shock wave that tinsel 9 vaporizations produce can cause glass tube 11 blasts to be measured, and the glass tube of sealing is placed in test board 10, and test board 10 is made by explosion-proof lamp, guarantees the safety of personnel in experimentation.
Experiment shows, this device is stable, reliable, can detect the size of different tubing shock resistances, current intelligence that can simulate flashlamp discharge.
