<\/p>\nHar du n\u00e5gonsin undrat hur effektiva dessa barri\u00e4rer placerade runt ambassader och andra federala byggnader \u00e4r? Forskare vid Texas A&M Transportation Institute sl\u00e4ppte video av en lastbil som kraschar in i barri\u00e4rer i 50 mph. Lastbilens hytt f\u00f6rst\u00f6rdes, men tunnor baktill, f\u00f6rmodat explosiva, f\u00f6rblev relativt oskadda.<\/p>\n
Detta var en simulerad terrorattack. Lastbilen var utrustad med ett fj\u00e4rrkontrollsystem och k\u00f6rdes in i en st\u00e5lbarri\u00e4r i 50 mph. Den 24 fot breda barri\u00e4ren \u00e4r begravd 18 tum ner i marken. Lastbilens vindruta och motorhuv rusar fram n\u00e4r kabinen f\u00e4lls ihop som ett dragspel. De svarta tunnorna p\u00e5 fordonets trailer som simulerade spr\u00e4ng\u00e4mnen hoppade n\u00e5gra centimeter upp i luften, innan restriktionerna \u00e5terf\u00f6rde dem till sin plats.![\"Barri\u00e4rkollisionsforskningsarbete6\"](\"https:\/\/blogging-techies.com\/wp-content\/uploads\/2020\/07\/Esto-es-lo-que-sucede-cuando-un-camion-golpea-una.jpg\")

M\u00e5let var att hindra lastbilsflaket fr\u00e5n att n\u00e5 mer \u00e4n en meter bortom barri\u00e4ren, en plats markerad med en bl\u00e5 stolpe. M\u00e5let uppfylldes eftersom ingen av lastbilsplattformarna n\u00e5dde den punkten. Detta test utf\u00f6rdes vid Texas A&M Transportation Institute Proving Grounds Research Center. Testet var utformat f\u00f6r att simulera terroristd\u00e5det som k\u00f6rde en lastbil lastad med spr\u00e4ng\u00e4mnen in i barri\u00e4rerna. Enligt institutet, “m\u00e5let med testet var att f\u00f6rhindra att lastbilens flaket passerar i 50 mph passerar en meter bortom barri\u00e4ren; flaket \u00e4r d\u00e4r en bomb kan vara, och det \u00e4r vad barri\u00e4ren ska beh\u00e5lla ut.” ‘![\"Barri\u00e4rkollisionsforskningsarbete5\"](\"https:\/\/blogging-techies.com\/wp-content\/uploads\/2020\/07\/1593633673_809_Esto-es-lo-que-sucede-cuando-un-camion-golpea-una.jpg\")

Det \u00e4r en del av TTis kontrakt med det amerikanska utrikesdepartementet att testa olika “perimeters\u00e4kerhetsanordningar” installerade p\u00e5 ambassader och andra anl\u00e4ggningar runt om i v\u00e4rlden. “M\u00e5let \u00e4r att f\u00f6rhindra att en terrorist bryter mot barri\u00e4ren,” sa Dean Alberson fr\u00e5n TTI:s Crashworthy Structures Program till Texas Tribune. Detta speciella krocktest involverade en 24 fot bred barri\u00e4r begravd 18 tum i marken, sa han. “Ingen lastbil klarade barri\u00e4ren, vilket markerade testet som en framg\u00e5ng,” sa Alberson. Enligt forskarna \u00e4r f\u00f6rarens \u00f6verlevnad inte ett prim\u00e4rt problem i s\u00e5dana scenarier.<\/p>\n
