Negative Poisson's ratio structure with three-dimensional characteristics and combination method thereof
The invention relates to a negative Poisson's ratio structure with three-dimensional characteristics and a combination method thereof, and belongs to the technical field of negative Poisson's ratio structures. The negative Poisson's ratio structure is composed of basic units. The combination method comprises the following steps: 1, the two-dimensional chiral negative Poisson's ratio structure basic units are placed in coincidence, and further one two-dimensional negative Poisson's ratio structure basic unit is linearly rotated by 90 degrees along a short axis direction to form an orthogonal three-dimensional basic unit, the two-dimensional negative Poisson's ratio structure basic units intersect and are fixedly connected to the equinoctial point of an inner rib, and each two-dimensional negative Poisson's ratio structure basic unit consists of four adjacent link points and five ribs associated with each other. The negative Poisson's ratio structure has the characteristics that the pressure is exerted in one determined direction and contraction is generated in the other two directions; and the combination method is simple and easy to implement.
本发明涉及一种具有三维特性的负泊松比结构及其组合方法，属于负泊松比结构技术领域。本发明由基本单元通过以下步骤形成：首先，将两个二维手性负泊松比结构的基本单元重合放置，进一步其中一个二维负泊松比结构基本单元沿短轴方向直线旋转90°形成正交的三维基本单元，两个二维负泊松比结构基本单元相交且固接于内肋的二分点处，每个二维负泊松比结构基本单元由相邻的四个环节点以及彼此关联的五根肋组成。本发明具有在一个确定方向上施加压力而另外两个方向产生收缩的特性；加工简单、易于实现。
