The invention relates to a bistable shell structure and a manufacturing method of the bistable shell structure. The bistable shell structure comprises a shell body and rib structures. The rib structures are buried into the shell body or protrude from at least one surface of the shell body. The manufacturing method of the bistable shell structure comprises the steps of rib structure formation and shell body formation, wherein the step of rib structure formation comprises embedded material formation or pre-formation conducted through a mold. The rigidity, strength and morphological transformation efficiency of the bistable shell structure can be effectively improved. Besides, because of the locally arranged rib structures, the weight of the bistable shell structure cannot be greatly increased. 本发明涉及种双稳态壳结构及其制造方法。本发明的所述双稳态壳结构包括壳本体和筋结构；所述筋结构埋覆于所述壳本体内部或凸出于所述壳本体至少个表面上。本发明的所述方法包括筋结构成型和壳本体成型；其中，所述筋结构成型的方法包括预埋材料成型或通过模具预成型；本发明的所述双稳态壳结构能有效提高双稳态壳结构的刚度、强度和形态转变效率，而且因为是局部设置的筋结构，也不会大幅度增加双稳态壳结构的重量。
