The invention provides a modularized cord-driven continuum mechanical arm. The modularized cord-driven continuum mechanical arm comprises a plurality of modularized single bodies, a first hinge joint part and a second hinge joint part are arranged on the opposite surfaces of every two adjacent modularized single bodies respectively, the first hinge joint part of one modularized single body and the second hinge joint part of the other corresponding modularized single body form a hinge joint structure, the modularized single bodies are sequentially in hinge joint through the hinge joint structures to form mechanical arm joints, and the modularized single bodies are provided with function holes and cord passing holes arranged circumferentially sequentially. The modularized cord-driven continuum mechanical arm has the advantage that through different connecting and locking modes adopted between every two adjacent modularized single bodies, different continuum mechanical arms different in flexibility and load capacity can be obtained.

The invention provides a fluid-solid coupling high-precision numerical simulation method based on continuous medium mechanics, and belongs to the technical field of fluid-solid coupling numerical simulation. The implementation method is as follows: based on an intrinsic non-oscillation (WENO) finite difference method, a joint algorithm coupled with a Level-Set method and a real virtual fluid method (RGFM), high-precision numerical simulation of fluid-solid coupling of continuous medium mechanics is realized. The WENO finite difference format can realize high-precision spatial discretization byselecting spatial template lattice points, so that the calculation precision is ensured, and the dissipation of shock waves is remarkably reduced; the Level-Set method can be used for effectively processing the complex topological structure change of the multi-substance interface; The RGFM method can effectively restrain the problem of non-physical oscillation generated by the interaction of shock waves and a material interface. The method can improve the prediction accuracy of the fluid-solid coupling process, and further solves the related engineering technical problems in the fluid-solid coupling field. The fluid-solid coupling field comprises the fields of high-speed penetration weapons, protection equipment, aerospace and mechanical engineering.
