Abstract

The invention relates to a tube pressure simulation type shock wave detection device. 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 [0001] The invention relates to a shock wave simulation inspection device, in particular to a shock wave detection device for simulating the pressure of a lamp tube. Background technique [0002] When the high-power pulsed xenon lamp discharges, the shock wave generated by the high-temperature xenon plasma will damage the material of the tube wall, and even destroy the material of the lamp tube in severe cases. This is the main reason for the explosion of the lamp. Whether the xenon lamp can be used safely and its service life. Experiments have proved that the load intensity of high-power pulsed xenon lamps is closely related to the material of the tube wall. One of the main reasons for lamp tube damage under high-power discharge conditions is that the radial shock waves generated by the gas in the lamp burst the tube wall. This situation is different. in static radial tension. Due to limited conditions, in the past, only the radial static tension test data...
