据美国陆军技术网站报道,美国陆军研究实验室与Alcoa公司正在合作研究单件铝合金车体,以增强车辆对IED威胁的防护。该车体是目前世界上最大的、计划替代现役地面战斗车辆的车体,以保证更高的强度和寿命。目前,服役车辆的车体是通过将几块金属装甲板焊接在一起形成车体结构件。这样焊缝常常变成薄弱区,变得对爆轰敏感。Alcoa公司执行副总裁Kay Klimer指出,该公司已研发出革新的长寿命和轻型铝合金技术。研究人员目前正在研究世界上最大的可防IED的战车车体,单件车体结构将不使用焊接装甲板。公司计划使用先进的吸收爆轰能的合金,进一步提高车体结构的损伤 According to the U.S. Army Technology website, the U.S. Army Research Laboratory and Alcoa are working together on a one-piece aluminum alloy bodywork to enhance the vehicle’s protection against IED threats. The body is currently the largest in the world and plans to replace the bodywork of active ground-based combat vehicles to ensure higher strength and longer life. At present, the bodies of service vehicles are formed by welding several metal armor plates together to form the car body structure. Such welds often become weak areas and become sensitive to detonations. Kay Klimer, Alcoa’s executive vice president, said the company has developed innovative long-life and lightweight aluminum alloys. Researchers are currently studying the world’s largest IED anti-tank body, a single body structure will not use the welding armor. The company plans to use advanced absorbing detonation of the alloy, to further enhance the body structure damage
