The invention provides a rigid shock insulation support for spacecraft single-machine product installation and a spacecraft, and relates to the field of spacecraft product installation structures, and the rigid shock insulation support comprises an installation seat, a porous arm, a U-shaped bend, a porous arm, an L-shaped bend and a connecting flange which are connected in sequence; and an angle of 80-90 degrees is formed between the mounting surface of the mounting seat and the mounting surface of the connecting flange. By means of the structural design, impact energy can be attenuated by a certain amplitude from the installation base to the bent position of each structure with the center hole, the U-shaped bend is a core attenuation node, the structural form of the U-shaped bend and the size of the center hole in the bent position have large influence on attenuation efficiency, and the U-shaped bend is different from a conventional damping dissipation structure. According to the specially-designed structural form, shock attenuation is achieved by blocking transmission of shock waves in the main transmission direction for multiple times, and protection of a single-machine product is facilitated.
本发明提供了一种用于航天器单机产品安装的刚性隔冲支架及航天器,涉及航天器产品安装结构领域,包括依次连接的安装座、多孔臂、U型弯、多孔臂、L弯以及连接法兰;所述安装座的安装面与连接法兰的安装面之间呈80°至90°角。通过结构设计,使得冲击能量由安装座经每一带中心孔的结构弯折处均可产生一定幅度的能量衰减,其中U型弯是核心衰减节点,U型弯的结构形式以及弯折处中心孔的尺寸对衰减效能影响较大,与常规阻尼耗散结构不同,该特别设计的结构形式通过多次阻断冲击波在主传递方向上的传递达成冲击衰减,有助于保护单机产品。
