项目摘要

(1) Study on the hybrid structure which is excellent in the crashworthiness and construction nature for side and bottom structure of shipAs a suitable side and bottom structure of ship, the hybrid structure, which is filled up with foaming material between two skin steel plates was examined, because this structure was supposed to have same or less weight and much more strength than the conventional stiffened panel. First, the parametric examination was carried out by changing the physical properties of foaming material, and the energy absorption feature was investigated. Next, the impact test was carried out and the dynamic strength characteristic was clarified. Furthermore, the fatigue and creep tests by three point bending were carried for the hybrid structure and the fundamental data to such strength was obtained.(2) Study on the hybrid structure which is excellent in the crashworthiness and applicable to vehicle other than shipIn recent years, it is required that the head part of a railroad vehicle should equip energy absorption structure.The hybrid structures which are filled up with foaming material in steel or aluminum column were examined as the structure which absorbs impact energy with constant reaction force.And it was shown clearly by both experiments and numerical calculation that this structure is promising as an energy absorption structure.

(1)具有优良耐撞性和施工性能的混合结构在船舶侧部和底部结构中的应用研究作为一种合适的侧部和底部结构，在两块蒙皮钢板之间填充泡沫材料的混合结构被研究，因为这种结构被要求与传统的加筋板结构相比具有相同或更轻的重量和更高的强度。首先，通过改变发泡材料的物性参数进行了参数检验，并研究了发泡材料的吸能特性。接着，进行冲击试验，明确动态强度特性。并对混合结构进行了三点弯曲疲劳和蠕变试验，获得了混合结构强度的基础数据。(2)耐撞性优良的适用于船舶以外车辆的混合结构研究近年来，针对铁道车辆头部需要设置吸能结构的问题，分别对在钢柱和铝柱中填充泡沫材料的混合结构进行了试验研究，结果表明，该混合结构在吸收冲击能量的同时，还能保持恒定的反力数值计算表明，这种结构是一种很有前途的吸能结构。
