Abstract
With the appearance of additive manufacturing processing technology, lattice structures exhibit a variety of novel properties, such as thermal conductivity, weight reduction, magnetic conductivity. In view of its effect on structural weight reduction, some scholars try to apply it to the design of bionic robot structure. There are specific conditions for its application, as lattice structure could reduce stiffness. In this paper, the stiffness of the lattice structure is studied by taking plate and pipe as the research content. At first, the influence of relative density and diameter of lattice rod on the stiffness of lattice packed plate under vertical force is studied. A mechanical model is established, and the optimal selection principle of relative density of lattice is proposed. Then, the stiffness variation of lattice filled pipe under vertical force and three-point bending condition is studied. It is found that lattice filling can be used to release stress in the structure, which will improve the energy absorption, and the suitable application scenario of lattice structure is given.
