摘要
为了研究特性材料拦阻系统(Engineered Material Arresting System,EMAS)的动力学模型,创造性地研究了泡沫混凝土材料的力学特性,建立了机轮/拦阻材料之间的静力学模型和拦阻系统的动力学模型,设计建造了专门的实验装置并用B737飞机对模型进行了试验验证。本研究提出的双侵彻实验方法可以较好地表征材料的力学性能;设计建造的台架实验装置能够研究机轮对拦阻材料的碾压机理;建立的机轮/拦阻材料间力学模型和飞机拦阻动力学模型通过了一系列试验验证。以该研究为基础形成EMAS产品,已经在8家机场安装了9套,创造直接经济效益2.9亿元。
For the modeling of the Engineered Material Arresting System(EMAS),the research creatively studied the mechanical properties of foamed concrete material,established the static model of LDG wheel/arresting material interface and the dynamic model of the arresting system,set up a special experimental facility,and used a Boeing 737 aircraft to verify the models.The double penetration test was proposed to characterize the mechanical properties of the material;the experimental facility was set up to study the rolling compaction of the wheel on the arresting material;a series of tests verify the mechanical model of wheel/arresting material and kinetic model of aircraft arresting.Based on this research,EMAS products have been formed,and 9 sets have been applicated in 8 airports,creating direct economic benefits of RMB 290 million.
