摘　　要：用正六边形代替实际蜂芯,推导了夹层结构的平压强度与芯子宽厚比的关系,并对八种规格的芯子平压强度进行统计,统计结果虽然与推导的结果有偏差,但规律却是一致的,即蜂窝夹层结构的平压强度随着芯子宽厚比d/t_s增大呈负指数减小。Using the hexagon instead of the actual honeycomb core,the flat compression strength of sandwich structure and its relationship with the width to thickness ratio was deduced. Eight kinds of specifications of core flat compressive strength were evaluated. Statistical results revealed that although there are deviations from the deduced results,the law is consistent,namely honeycomb sandwich structure of flat compression strength decreases exponentially with the increase of core width to thickness ratio d/t_s.
