Three-dimensional auxetic structure based on anti-chirality four-arm missing strut configuration

The embodiment of the utility model provides a three-dimensional auxetic structure based on a reverse chirality four-arm missing strut structure, and relates to the field of auxetic materials. The deformation amount of the auxetic structure under the auxetic effect is increased. Comprising a plurality of basic units; the basic unit comprises an upper annular piece, a lower annular piece, twelve inclined rods, eight supporting columns and eight arms which are arranged in the space; the four supporting columns on each layer are distributed in the circumferential direction of the swastika-shaped piece at intervals. One ends of the four supporting columns are connected with the center position of the annular piece, and one ends of the four supporting columns of the swastika-shaped piece are connected with one ends of the four corresponding arms in a one-to-one mode. The two arms of any two basic units are connected; and the upper and lower swastika-shaped pieces are connected at intervals in a staggered manner th
