Pulsed pPulsed photoacoustic wave dispersing shield

Main tactical and technical indexes:

1) Strike-resistance strength: It can withstand strike at 18m/s speed and 350 joules energy at -30℃ ~ 55℃, without breaking of shield body and falling off of observation window.

2) Puncture-proof performance: It can withstand puncture at 147 joule kinetic energy. The aperture diameter of punctured point of the shield body is < 6mm, without breaking of shield body.

3) Anti-impact strength: It can withstand impact of 147 joule kinetic energy, without breaking of shield body and falling off of observation window.

4) Anti-cutting performance: The shield can withstand cutting of the cutting test machine at linear speed of the cutting point 8.5m/s ± 0.3m/s and energy 100J ± 5J, and the sample after the test is not cut off.

5) Mechanical environment suitability: the shield can work normally after sine vibration test (10 Hz - 55 Hz, 0.35mm, 1 octave/min, and 30min in three axial directions).

6) Acoustic wave dispersing unit performance: Maximum sound pressure level at ahead of the shield: 1m, 130dB;
