The invention relates to the technical field of microgravity measurement, in particular to a buffering and fixing structure for a microgravity double-body falling cabin and the microgravity double-body falling cabin, and the buffering and fixing structure comprises a buffering block and a plurality of arrowheads which are arranged on the bottom surface of an inner cabin; the buffer block is arranged on the inner bottom surface of the outer cabin below the arrowhead; in a microgravity test experiment, when a cabin body falling test is finished, through the matching effect of an arrowhead at the bottom end of the inner cabin and a buffer block on the inner bottom surface of the outer cabin, buffer deceleration is formed on the inner cabin, kinetic energy of the inner cabin is absorbed, direct collision between the inner cabin and the outer cabin is prevented, and the inner cabin is fixed through the friction force between the buffer block and the arrowhead; compared with a traditional mechanical fixing structure, the arrowhead-buffer block provided by the invention has the advantages that the structure is simple, the speed reduction process is soft and uniform, and secondary damage to parts is avoided; the problem that in microgravity measurement in the prior art, due to collision or rebounding between an inner cabin and an outer cabin, structures and instruments in the cabins are damaged is solved.
本发明涉及微重力测量技术领域,具体为一种用于微重力双体落舱的缓冲固定结构及微重力双体落舱,包括缓冲块和若干利镞,所述利镞设置于内舱的底面上;所述缓冲块设置于利镞下方的外舱内部底面上;在微重力测试实验中,可在舱体坠落试验结束时,通过内舱底端的利镞和外舱内部底面上的缓冲块的配合作用,对内舱形成缓冲减速,吸收内舱的动能,防止内、外舱的直接碰撞,并通过缓冲块与利镞间的摩擦力固定内舱,达到防止其反弹的效果,相比于传统的机械固定结构,本发明提供的利镞‑缓冲块,结构构造简单,且减速过程柔和均匀,不会对零件造成二次伤害;解决了技术中存在的在微重力测量中,内舱和外舱之间碰撞或反弹导致的舱内结构和仪器受损的问题。
