The invention discloses a momentum wheel integrated vibration reduction support which comprises a bottom plate, a shell, a mounting flange and a vibration reduction pad. The bottom plate is fixedly connected with a satellite structure through a damping pad, and a shell used for supporting the four momentum wheels is arranged above the bottom plate. Except the bottom plate, the shell body is a nonahedron, the four large mounting flange faces are used for mounting the four momentum wheels respectively, the four small planes are used for connecting the shell and the bottom plate, and structural reinforcement is conducted in a reinforcing rib mode. Through the cooperation of the bottom plate, the shell, the mounting flange and the anti-vibration pad, multiple momentum wheels are mounted to the maximum extent in the upper limit space of a satellite, lightweight design analysis is conducted at the same time, the weight is reduced, meanwhile, the overall mechanical property of the support is optimized, and the stability of the support is improved. The defect that the machining precision of a traditional large thin-wall metal part is difficult to guarantee is overcome in a 3D printing mode, and the problems that the occupied effective installation size on a satellite is large due to independent installation, and load disturbance is large due to micro-vibration generated by operation of the momentum wheel are solved.
本发明公开了一种动量轮一体化减振支架,包括底板、壳体、安装法兰和减振垫;底板通过减振垫与卫星结构固定连接,底板上方是用于支撑共四个动量轮的壳体。除去底板,壳体本体为九面体,四个大的安装法兰面用于分别安装四个动量轮,四个小平面用于壳体与底板之间的连接,且通过加强筋形式进行结构补强。本发明通过底板、壳体、安装法兰和减振垫的配合,实现了在星上极限空间内,最大限度安装多台动量轮,同时进行轻量化设计分析,减轻重量的同时优化了支架整体的力学特性,通过3D打印形式弥补了传统大型薄壁金属件机加精度难以保证的缺陷,克服了单独安装占用星上有效安装体积大且动量轮运行产生的微振动对载荷扰动大等难题。
