摘要: 蜂巢板独特的结构使其具有较高的比弹性率(E/ρ),在大尺寸活塞辐射换能器中具有重要的应用价值,蜂巢数量巨大使仿真所耗电脑资源大,甚至得不到结果。本文以蜂巢活塞板为,研究了蜂巢密度对力学性能的影响,提出了蜂巢板分析的等效,进一步了蜂巢板受力变形公式,了力学相似模型。研究结果表明:蜂巢板和蜂巢密度反相关,相似模型。本研究为蜂巢板在大尺寸活塞辐射换能器中的应用奠定了一定的技术基础。

Abstract: Honeycomb board is valuable on large dimesion transducers with piston, for elastic modulus ratio of its structure is big. When honeycomb board is analyzed by limited-element method, much computer resource is needed for nuch honeycombs. On the basis of honeyconb board, we have studied one-layer equivalent board and three-layers equivalent board, analysed the influence of hoenycomb density on mechanical properties, the equivalent method has been given, and the deformation formula is derivated to get mechanics sinilarity models. The results indicated that three-layers equivalent board is better to be honeycomb board equivalent model, the deformation had the reverse correlation with honeycomb density, the maximum error of mechanical-similarity model was only 1.62%. The results are of great importance for the application in transducers with large dimension piston
