摘要： A shock absorber system was designed to absorb the energy imparted to doors in a nuclear reactor ice condenser compartment as they swing rapidly to an open position. Each shock absorber which is installed on a wall adjacent each door is large and must absorb up to about 40,000 foot pounds of energy. The basic shock absorber component comprises foam enclosed in a synthetic fabric bag having a volume about twice the foam volume. A stainless steel knitted mesh bag of the same volume as the fabric bag, contains the fabric bag and its enclosed foam. To protect the foam and bags during construction activities at the reactor site and from the shearing action of the doors, a protective sheet metal cover is installed over the shock absorber ends and the surface to be contacted by the moving door. With the above shock absorber mounted on a wall behind each door, as the door is forcibly opened by steam pressure and air resulting from a pipe break in the reactor compartment, it swings at a high velocity into contact with the shock absorber, crushes the foam and forces it into the fabric bag excess material thus containing the foam fragmented particles, and minimizes build-up of pressure in the bag as a result of the applied compressive force.
摘要翻译： 设计了一种减震器系统，用于吸收在核反应堆冰冷凝器舱内迅速摆动至打开位置时施加给门的能量。 安装在每个门附近的墙壁上的每个减震器是大的，并且必须吸收高达约4万英尺磅的能量。 基本的减震器部件包括封闭在具有约两倍泡沫体积的体积的合成织物袋中的泡沫。 与织物袋相同体积的不锈钢针织网袋包含织物袋及其封闭的泡沫。 为了在反应堆场所的施工活动期间和门的剪切作用下保护泡沫和袋子，在缓冲器端部和被移动的门接触的表面上安装有保护金属板盖。 将上述减震器安装在每扇门后面的一个墙壁上，当门被反应室内管道破裂所产生的蒸汽压力和空气强行打开时，它以高速摆动与缓冲器接触，将泡沫压碎 并将其压入织物袋过剩的材料中，从而包含泡沫碎片颗粒，并且由于施加的压缩力，使袋中的压力积聚最小化。

摘要： An air box type shock absorber primarily for use in an ice condenser compartment of a nuclear reactor. The shock absorber includes a back plate member and sheet metal top, bottom, and front members. The front member is prefolded, and controlled clearances are provided among the members for predetermined escape of air under impact and compression. Prefolded internal sheet metal stiffeners also absorb a portion of the kinetic energy imparted to the shock absorber, and limit rebound. An external restraining rod guided by restraining straps insures that the sheet metal front member compresses inward upon impact.
