【摘要】 本文主要研究聚氨酯硬泡制作重载低RCS泡沫支架的可行性,通过试验研究比较了聚氨酯泡沫与EPS泡沫的力学特性和电学特性,并利用波恩近似以及体散射公式对聚氨酯泡沫支架进行了设计仿真,最后实际制作承重10吨以上的聚氨酯泡沫支架,并在紧缩场中进行了测试,测试结果证明了聚氨酯泡沫支架在重目标RCS测试中的优越性。更多还原

【Abstract】 This article mainly research the feasibility of using polyurethane hard foam to make a low RCS foam heavy target support system.First,compare the polyurethane foam and EPS foam’s mechanical properties and electrical properties through experimental studies.Then design and simulate the foam target support system using born approximation and Body scattering formula,Finally.manufacture a PU foam support system that can bearing at lest 10 tons target,and tested in the Compact Range.The test result proven the PU foam support system has good performance in heavy target RCS measurement.更多还原
